FIX:
- Remove unnecessary files from git repo
- replace outdated nosetests -> pytest as test running
IMPROVEMENTS:
- Improve handling of HOG IDs in pyham. HOG objects use "hog_id" or "og" attribute
from orthoxml to show objects, and also include the taxonomic range.
- LOFT attribute will be loaded for gene elements if assigned in orthoxml.
