Marisa-trie-m

------------------

* Small code cleanup;
* ``load``, ``read`` and ``mmap`` methods returns 'self';
* I can't run tests (via tox) under Python 3.3 so it is
removed from supported versions for now.

------------------

* ``.prefixes()`` support for RecordTrie and BytesTrie.

----------------

* RecordTrie and BytesTrie are introduced;
* IntTrie class is removed (probably temporary?);
* dumps/loads methods are renamed to tobytes/frombytes;
* benchmark & tests improvements;
* support for MARISA-trie config options is added.

------------------

* Pickling/unpickling support;
* dumps/loads methods;
* python 3.3 workaround;
* improved tests;
* benchmarks.

----------------

Initial release.
