	@brief Main Interface Object
	@details
		+ The CKContext object is the heart of all Virtools based applications, It is the first object that should be created in order to
		use Virtools SDK. A CKContext can be simply created by calling its constructor.
		+ The CKContext object act as the central interface to create/destroy objects,to access managers, to load/save files.
		+ Several CKContext can be created inside a same process (in multiple threads for example) but objects created
		by a specific CKContext must not be used in other contextes.
