allow non-unique file names; match metadata based on unique file paths

[gszep]

The issue is cross-platform compatibility. FlowJo stores the absolute path that contains os user specific information that we do not want to parse. I currently use basename(path) to uniquely identify the sample in the .wsp file, but this is not general. How do I truncate path to the relative path of the .fcs file from the .wsp file?
