Book shelf 772 - now with even more parameters!  Adjust width, height, depth, and number of shelves (from 1 to 6).  Books can be turned on and off. 

Update: In response to some comments about the file size, I've uploaded a version of this this that's been slimmed down significantly.  Appearance and function are still the same.
