Helper functions for implementing core functionality. This namespace
should not be treated as public. Functions inside this namespace are
subject to change and meant as helper functions for the core.

Protocols to control and extend the behavior of core clj-fdb functions.

These are marked as internal at the moment since I am still working
through the shape of the interfaces. I will make this namespace
public by the 1.0 release.

* `Encodable` -- for producing new Byte-Array objects to insert into FDB.
* `Decodable` -- for converting back Byte-Array objects returned by FDB.

A set of operations that can be performed atomically on a database.
These are used as parameters to `ftr/mutate!` (mutation, byte[],
byte[]).

A simple description of an exact range of keyspace, specified by a
begin and end key. As with all FoundationDB APIs, begin is
inclusive, end exclusive.
