/**
	This class implements the MoveElementsHandler Strategy class.
	It acts like a BasiMoveElementsHandler configured to answer QET::Abort to any question.
	Please note this class was designed with the context of integrating an element definition into a project in mind.
	For this purpose, the elementAlreadyExists method was redefined to ask users whether they wish to:
	  * erase a different, already-existing element,
	  * keep the already-existing element by renaming the new one,
	  * or cancel the integration.
