Oops
Oo , don't use "Re-arrange code" in intellij anymore
Allows to specify your own global packing constraint.

This is not a very convincing approach. Why not relying on solver-only views ? Much more scalable in terms of API too (I am fed off augmenting RP & co)
- Externalize the Cumulatives Builder
- Simplify a bit the instantiation of the RP
javadoc
remove the redundancy between useLabel() and the algorithm parameters
Remove some useless methods
Packing as a view, but a slightly different view. Both a better and a worse approach.

Better at the usage, but reveal dependency issues between core and external views
Refactor Cumulatives and AliasedCumulatives as core views.

Still some work to do to make this cool.
clean a bit
ChocoModelView -> ChocoView

minor cleaning and documentation.
Try to make uniform model view mappers and solver views. Not particularly proud of that for the moment
merge checker package into its parent.
Merge branch 'develop' into refactorChocoViews
javadoc
minor improvments
documentation & minor code quality improvements
code simplifications
