k3-sle: New EMF-aware JVM types builder
k3-sle: NamingHelper coding style
k3-sle: Cleaning up typing
k3-sle: Checking for commented generated code is now useless
k3-sle: Generate isSet/unset methods based on genmodel annotations
k3-sle: FQN makes sense for ModelType too
(tl;dr)

- Ecore generics are supported by the inferrers
- But for now type parameters are fixed (i.e. not abstracted) as we don't know how to create adapters for such types
- Better decomposition of jvm inferrers
