Process for composite key (parent key + number) does not work

[Yves Drumbonnet]

Change the way to compute composite key.
Add a column compositeKeyStrategyFactoryClassName in tree entityTree.
By default, in EntityScenario class, a standard composite key factory is set when a key (parent key, increment) is detected.

Developers can write their own composite key strategy and link it to Entity type.
An other simplest way is to define a Callfore class (callback launched from the client side) or a Callback (server side) which computes the key (identifier) for the persisted bean.
