* NAME
* Pointer Vector
*
* DESCRIPTION
* The Pointer Vector is a self-sizing array of pointers. Like a traditonal
* array, a pointer vector allows efficient constant time access to elements
* with a specified index. A pointer vector grows transparently as the
* user adds elements to the array.
*
* The cl_pointer vector_t structure should be treated as opaque and should be
* manipulated only through the provided functions.
*
* SEE ALSO
* Structures:
* cl_ptr_vector_t
*
* Callbacks:
* cl_pfn_ptr_vec_apply_t, cl_pfn_ptr_vec_find_t
*
* Item Manipulation:
* cl_ptr_vector_set, cl_ptr_vector_obj
*
* Initialization:
* cl_ptr_vector_construct, cl_ptr_vector_init, cl_ptr_vector_destroy
