Updated files...see notes-------------------------------------------> I added the functions VIDEO-CAPTURE-GRAB, GRAB, VIDEO-CAPTURE-RETRIEVE, RETRIEVE, GET-NUMBER-OF-CPU-S, and FOUR-CC.  I added examples and documentation for all but FOUR-CC. Fixed the todo in examples.lisp for FOUR-CC. Fixed GC in some of the examples in examples.lisp and improved the look by finishing the separators between the documentation for each function. Reordered some of the documentation.
