Combine nexus columns with two or more nucleotides into a single nexus matrix.

For additional help:

&> ./run.py -h

To run:

&> ./run.py inputFile outputFile [either 'all' or 'sample']

all vs. sample options:

'all' option includes every column with two or more nucleotides.'sample' chooses one 'random' column from all of the columns in each matrix.

Note: this library depends on python-nexus library, install with

&> sudo pip install python-nexus

If you don't have pip installed, first call

&> sudo easy_install pip
