## Building a FormalContext
We use the example from https://en.wikipedia.org/wiki/Formal_concept_analysis:
~~~nit
var fc = new FormalContext[Int, String]
fc.set_object_attributes(1, ["odd", "square"])
fc.set_object_attributes(2, ["even", "prime"])
fc.set_object_attributes(3, ["odd", "prime"])
fc.set_object_attributes(4, ["even", "composite", "square"])
fc.set_object_attributes(5, ["odd", "prime"])
fc.set_object_attributes(6, ["even", "composite"])
fc.set_object_attributes(7, ["odd", "prime"])
fc.set_object_attributes(8, ["even", "composite"])
fc.set_object_attributes(9, ["odd", "square", "composite"])
fc.set_object_attributes(10, ["even", "composite"])
~~~
## Computing the set of FormalConcept
~~~nit
var concepts = fc.formal_concepts
for concept in concepts do
print concept
end
~~~
## Visualizing formal concept with ConceptLattice
~~~nit
var cl = new ConceptLattice[Int, String].from_concepts(concepts)
cl.show_dot

Merge: nitunit: use annotations
This PR replace the name heuristics used by nitunit by nice and tidy annotations.
Before:
~~~nit
module test_my_test is test_suite
import test_suite
class TestMyTest
super TestSuite
redef fun before do # something
fun test_my_test do
assert true
end
end
~~~
After:
~~~nit
module my_test is test
class MyTest
test
fun setup is before do # something
fun my_test is test do
assert true
end
end
~~~
Motivations:
* cleaner API / naming policy
* [BDD](https://en.wikipedia.org/wiki/Behavior-driven_development) friendly
* more flexibility as one can define a `after` method in the lib that will only be executed on children module tagged with `test`
* more extensible as one can improve nitunit to support `test(timeout = 150)` or `test(res= "res/test_file.res")`
Used annotations:
* `test` on modules, classes and properties to indicate that nitunit must run this module/class/method
* `before`, `after` on properties from all classes but `Sys` for the before/after each case hooks
* `before_all`, `after_all` on properties from `Sys` for the before/after all cases hooks
This also removes the need of the `lib/test_suite` module.
I also migrated the existing test suites to the new annotations system. Let's see what Jenkins has to say about it.

Merge: Intro MessagePack serialization engines
MessagePack is a portable data serialization format. It differs from JSON by its binary format, compressing common types, support for custom types and accepting any object as map key. Here, the primitive Nit types use the shortest available MessagePack format (e.g. an `Int` between -32 and 127 takes a single byte). The custom types are used to declare some metadata and special types (objects, references, `Char`, etc.). The engines can, optionally, benefit from the map keys as any object to compress repeated metadata (class and attribute names).
These engines should replace the current `Binary::serialization` services, which are almost impossible to debug, less compressed than MessagePack and not standard.
The serialization engine supports writing and reading plain (no metadata) MessagePack data, similarly to the JSON engines.
Most clients should use the high-level services:
* Customizable engines to handle errors: `MsgPackSerializer` and `MsgPackDeserializer`.
* Quick services on streams: `Writer::serialize_msgpack` and `Reader::deserialize_msgpack`.
* Quick services on `Bytes` (mostly for testing): `Serializable::serialize_msgpack` and `Bytes::deserialize_msgpack`.
Or, to write engines one can use the low-level services:
* Low-level writing methods: `Writer::write_msgpack_uint64`, `Writer::write_msgpack_bin8`, etc.
* Low-level reading method: `Reader::read_msgpack`.
---
Using it in Jwrapper, the MessagePack format creates smaller files than JSON (at ~50% the size), when using the default options and serializing the metadata of the Java standard library:
* JSON: 14.9 MB
* MessagePack (default): 7.0 MB
* Old binary: 9.8 MB
The file gets shorter in plain MessagePack mode or when caching the metadata strings:
* MessagePack `plain_msgpack=true`: 6.3 MB
* MessagePack `cache_metadata_strings=true`: 3.0 MB
Caching metadata creates much smaller files, however for the size only gzip has a bigger effect.
Further investigations is required to see the impact it has on the speed.
* gzipped MessagePack (default): 0.7 MB
* gzipped MessagePack `cache_metadata_strings=true`: 0.6 MB
---
This PR depends on #2539 as it works on binary data, you can ignore the first 2 commits.
@R4PaSs you may want to look at the commits modifying `Int::to_bytes` and `Bytes::to_i`.

Merge: serialization: redef inspect for an output useful to humans
Intro a new serialization engine to pretty print the attributes of the receiver on calls to `inspect`. The format is designed to be helpful, reproducible and compact.
Note that, asides from direct calls to `inspect`, this will also affect the default behavior of `Serializable::to_s`. And this will not affect all Nit programs, but it will affect all those importing the serialization services, so most larger projects using either `json`, `nitcorn`, `gamnit`, `more_collections`, etc.
Simple immutable data are inspected as they would be written in Nit code:
~~~
assert 123.inspect == "123"
assert 1.5.inspect == "1.5"
assert 0xa1u8.inspect == "0xa1u8"
assert 'c'.inspect == "'c'"
assert "asdf\n".inspect == "\"asdf\\n\""
~~~
Inspections of mutable object show their dynamic type and an id unique to each call to `inspect`. A change from using their `object_id`.
Items of collections are flattened:
~~~
assert [1, 2, 3].inspect == "<Array[Int]#0 [1, 2, 3]>"
var set = new HashSet[Object].from([1, 1.5, "two": Object])
assert set.inspect == """<HashSet[Object]#0 [1, 1.5, "two"]>"""
var map = new Map[Int, String]
map[1] = "one"
map[2] = "two"
assert map.inspect == """<HashMap[Int, String]#0 {1:"one", 2:"two"}>"""
~~~
Inspecting other `Serializable` classes shows the first level attributes only:
~~~
class MyClass
serialize
var i: Int
var o: nullable Object
end
var class_with_null = new MyClass(123)
assert class_with_null.to_s == class_with_null.inspect
assert class_with_null.to_s == "<MyClass#0 i:123, o:null>"
var class_with_other = new MyClass(456, class_with_null)
assert class_with_other.to_s == "<MyClass#0 i:456, o:<MyClass#1>>"
var class_with_cycle = new MyClass(789)
class_with_cycle.o = class_with_cycle
assert class_with_cycle.to_s == "<MyClass#0 i:789, o:<MyClass#0>>"
~~~
Inspections producing over 80 characters are cut short:
~~~
var long_class = new MyClass(
123456789, "Some " + "very "*8 + "long string")
assert long_class.to_s == "<MyClass#0 i:
123456789, o:\"Some very very very very very very very very long s…>"

The only differences between the string and bytes streams are the behavior of `StringWriter::to_s` and the `String` parameter expected by the constructor of `StringReader`.
`BytesWriter` supports writing any bytes, including composing UTF-8 characters byte by byte, a behavior also useful for `StringWriter`:
~~~
var writer = new BytesWriter
# Write just the character first half
writer.write_byte 0xC2u8
assert writer.to_s == "\\xC2"
assert writer.bytes.to_s == "�"
# Complete the character
writer.write_byte 0xA2u8
assert writer.to_s == "\\xC2\\xA2"
assert writer.bytes.to_s == "¢"
~~~
`BytesReader` also supports reading any bytes, including the bytes composing an UTF-8 character for `StringReader`:
~~~
var reader = new BytesReader(b"a…b")
assert reader.read_char == 'a'
assert reader.read_byte == 0xE2u8 # 1st byte of '…'
assert reader.read_byte == 0x80u8 # 2nd byte of '…'
assert reader.read_char == '�' # Reads the last byte as an invalid char
assert reader.read_all_bytes == b"b"
~~~

Merge: app.nit: easier root window selection and other misc improvements
Intro the hook `root_window` for clients to set the desired root (or home) window. It is much shorter than the previous redef of `on_create`. Plus, in very simple apps, the client can simple redef `Window` instead of subclassing it.
Refactor `data_store` structure, replacing the interface and subclasses by refinements of a single class. It follows more closely the strategy used by the UI API while not changing anything to the `data_store` API. The data store now drops potentially partially deserialized objects to avoid hard to report crash at runtime, this could be improved upon in the future as the current implementation is not ideal.
Otherwise, this PR brings general improvements to the framework influenced by the creation of [paninit.com](http://paninit.com/): revamp the documentation, add unit tests, fix the scientific calculator icon and add an option to report errors in `hightlightcode`.

Merge: Nitweb: boost response time and some improvements
The main objective of this PR is to shorten the frontend response time.
The major culprit was that the full documentation was serialized in each response.
This PR makes nitweb return only the synopsis and lets the frontend ask for the full documentation if needed.
Also uniformizes and cleans tabs for entities:
* Moved data between tabs (such as inheritance data to the inheritance tab)
* Added missing tabs for packages and groups (http://nitweb.moz-code.org/doc/core%3Ecollection%3E/defs)

* Move up some general deserialization services from `json` to `serialization` in order to make them available to other engines. This includes the class name manipulation services and safety services controlling which types are deserialized, including `class_inheritance_metamodel`.
* Support writing and reading `Byte` as either a plain JSON string or a special object with metadata.
* Support reading `Char` and `Byte` from plain JSON input using simple heuristics.
* Test the deserialization of plain generated JSON and fix a typo in the tests.
* Fix other minor issues in code.

Merge: gamnit: shadow mapping
Intro a basic API and the shaders for 3D actors to cast shadows. This feature is off by default, it can be activated by using a sun-like light with: `app.light = new ParallelLight`. This will require additional work to improve the performance, add more kind of lights (point, spotlight, ambient, etc.), support many lights and accept colored lights.
Many values can be tweaked to achieve the best performance tradeoff:
* `ParallelLight` is always centered on the `world_camera` to show shadows only around the player. Its attributes `width, height, depth` are in world coordinates and identify a prism where shadows are computed. Higher values show shadows further away and lower values show shadows in higher resolution.
* `App::shadow_resolution` sets the resolution of the depth texture. Higher is prettier but slower, there's also an upper limit depending on the hardware configuration. It is now hardcoded (but refinable) to 4096x4096 pixels, with is probably too high for some mobiles devices. More experimentation is needed to find a safe default value.
* For softer shadow edges, the shader applies a kind of antialiasing by tapping the depth texture many times for each fragment. It is currently hardcoded to 4 taps per fragment but it could be changed for better performances or smoother edges. I don't know where to expose this value in the API, it could be on the light, the material or even global. It can also be optimized by the hardware.
