package SelectBasics 

	---Purpose:  kernel of dynamic selection:
	--           - contains the algorithm to sort the sensitive areas
	--           before the selection action;->quick selection of
	--           an item in a set of items...
	--           - contains the entities able to give the algorithm
	--             sensitive areas .
