Object oriented OOP

[elucian]

Bee is going OOP. Most languages use keyword "class" to define data type. We consider Bee to use a reduced number of keywords and we use keyword "type" to define a new data type. In this regard, Bee is inspired from Ada not form Java.

We define symbol "<:" instead of keyword "extend". The root class will be: "Object" or "O" these two are synonyms. We will use term: "Companion" instead of "Constructor". That is for a data type you can have a companion rule, that define object behavior.
