quota quotation

Word description
Creates a quotation that when called, has the same effect as applying case to assoc.

This word uses three strategies:
If the assoc only has a few keys, a linear search is generated.
If the assoc has a large number of keys which form a contiguous range of integers, a direct dispatch is generated using the dispatch word together with a bounds check.
Otherwise, an open-coded hashtable dispatch is generated.
