Disabling 'Sequence Length Histogram' on Metagenome Overview page when all sequences are the same length, $len_min == $len_max
Merge branch 'develop' of https://github.com/MG-RAST/MG-RAST into develop
Fixed axis on PCoA plot when min == max.  The axis had no range and thus was being displayed incorrectly in this case.
Fixing path to index file for pairend joining.
Fixed bug in source field on Analysis page.  Was preventing users from downloading sequences from the workbench when they used "Representative Hit" to do their Analysis.
