Polished and moved files in cpath2-impl and biopax-impl in preparing for cpath2-impl removal and upgrading biopax reader plugin
(in Cy 3.1, biopax-impl will read BioPAX data and optionally convert to SIF or SBGN and delegate to corresp. apps, if any…)
Removed all services from the cpath2-impl bundle app (it's deprecated; will remove from the impl-parent and features.xml and move the sources out later)
