Module cursor 

Traits and types for navigating order sequences of update tuples.

The Cursor trait contains several methods for efficiently navigating ordered collections of tuples of the form (key, val, time, diff). The cursor is different from an iterator both because it allows navigation on multiple levels (key and val), but also because it supports efficient seeking (via the seek_key and seek_val methods).
