Treeomics submodules are not installed

[J-Moravec]

When installed with:

pip install git+https://github.com/reiterlab/treeomics

any treeomics submodules/packages (phylogeny, plots, utils) are not installed.

This is due to a malformed setup.py script. This can be fixed by simply commenting out the definition of packages on line 10 and uncommenting the one on line 9.

Change:

    packages=['treeomics', 'tests'],  # 'treeomics.phylogeny', 'treeomics.plots', 'treeomics.utils'],

to

      packages=setuptools.find_packages(),
