Dilute 0.0.1

Implement Filter

Implement an iterator filter that accepts a filter function that returns -1 to indicate that the value should be skipped, 0 to indicate that the value should be used, and 1 to indicate the end of iteration. The iterator is an iterator decorator. It exposes the same interface as the other MVCC iterator filters.
