Touch The genes.fpkm_Tracking file before use so it's easier to parallelize those steps between servers
Hatch-out NaN genes instead of deleting them.

Includes changes to both PlotUtils and MakeComparison files.
Convert low-mapping efficiencies to NaNs instead of dropping

Changes both in MakeSummaryTable and in Makefile which calls it.
Shorten the number of significant figures printed

It's unlikely we have more than 2 sigfigs anyways, and this makes making tables
a whole lot easier.
Merge branch 'BcdRNAi'

Feature changes including hatching in PlotUtils.svgwrite, filtering on low
mapping density, and outputing NaNs instead of dropping.
