Added Pjotr's latest pylmm changes...Added GEMMA and necessary plink-format genotype files in gemma directory
Added the GEMMA genotype files to git LFS
Removed some unnecessary/duplicated code from interval_mapping.py
Separated GEMMA mapping code into its own file (will also do this for other methods) and fixed
and issue that caused it to not run
Added the table to the pair scan results page and wrote some code adding its attributes
to each marker object, but it still isn't working yet
