A Cython wrapper around uShuffle - a useful tool for shuffling biological sequences while preserving the k-let counts

This is just a bundle of files downloaded from `ushuffle <http://digital.cs.usu.edu/~mjiang/ushuffle/>`_
and wrapped in Cython for easy installation and use.

Installation
------------

.. code-block :: bash

    git clone https://github.com/guma44/ushuffle.git
    cd ushuffle
    python setup.py install [ --user ]

or

.. code-block :: bash

    pip install [--user] ushuffle

Usage
-----

The library exposes a shuffling function shuffle and a Shuffler object used to
make shuffling many times eg.:

.. code-block :: python

    from ushuffle import shuffle, Shuffler
    seq = "ababcdcdabdcabvababab"
    shuffler = Shuffler(self.seq, 2)
    for i in range(10):
        seqres = shuffler.shuffle()
        print("results:", seqres)
    print shuffle(a, 2)
