[galaxy-commits] commit/galaxy-central: jgoecks: Trackster improvements: (1) add trackster_conf tag to tool definition; for now, tag indicates that tool is compatible with trackster, but will have configuration information in the future; (2) use trackster_conf tag to indicate that Cufflinks, gops intersect, and gops subtract are compatible with Trackster; and (3) remove .track_type attribute and use of it and use instanceof operator instead.
