LispCourse #33:  Solutions for Homework #32
Note
This solution differs slightly from the assignment.  Instead of keeping global pointers called LC.Head and LC.Tail, I created a record called LC.Queue with Head and Tail fields (as well as a field to indicate the last operation done on the queue to be used in the empty and full predicates).   This scheme allows multiple queues to be created at once, each with its own head and tail pointers.
