[Core] Add concept inheritance

[yuripourre]

Attributes can be reduced and probably kept updated if concepts have a "set" of super classes.

Horse -> Mammal -> Animal (so it has all the properties that animal+mammal has plus specific ones).

Little Horse -> Horse Little Horse -> Little

Inference: Horse is Animal

It can also make all the concepts more dynamics because if we change a superclass all related classes will update.

[yuripourre]

It reduces every concept to:

• What it is (Concept)
• What it has (Concept - quantity?) Possess
• What it can do (Action)

[yuripourre]

One optimization can happen when the concept "is" another kind of concepts, some attributes can be removed.
