/****h* Component Library/Vector
* NAME
*	Vector
*
* DESCRIPTION
*	The Vector is a self-sizing array. Like a traditonal array, a vector
*	allows efficient constant time access to elements with a specified index.
*	A vector grows transparently as the user adds elements to the array.
*
*	As the vector grows in size, it does not relocate existing elements in
*	memory. This allows using pointers to elements stored in a Vector.
*
*	Users can supply an initializer functions that allow a vector to ensure
*	that new items added to the vector are properly initialized. A vector
*	calls the initializer function on a per object basis when growing the
*	array. The initializer is optional.
*
*	The initializer function can fail, and returns a cl_status_t. The vector
*	will call the destructor function, if provided, for an element that
*	failed initialization. If an initializer fails, a vector does not call
*	the initializer for objects in the remainder of the new memory allocation.
*
*	The cl_vector_t structure should be treated as opaque and should be
*	manipulated only through the provided functions.
*
* SEE ALSO
*	Structures:
*		cl_vector_t
*
*	Callbacks:
*		cl_pfn_vec_init_t, cl_pfn_vec_dtor_t, cl_pfn_vec_apply_t,
