If you use a bitop against a frequently changing bitmap, the multi can be cancelled because the underlying key tracked by watch will change and invalidate the transaction. The biota will then return invalid results (0). This removes the transaction block. Unknown if this is dangerous if the bitmap is in the process of being copied. Causes bitops to not be strongly consistent.
The chunk_keys method is frequently used and relies on Redis's keys operator, which is costly for instances with large numbers of keys. This instead relies on a Redis set to track chunks, and significantly improves performance.
In testing large bitmaps saw a ~50x increase in speed by pipelining operations.
Updates readme to use github markdown :)
