Began work on common GTFS Function class to consolidate duplicated code.  Addressing one function, in particular, filePath.  Now that the sqlite database can be in multiple locations, choosing the correct one will need to be the priority.  This will eventually tie into the app shipping only the zipped version of the database.  If the file can't be found at startup, the bundled zip file will be uncompressed and moved to the common directory.
Wonderful\!  The new class that I created was nearly identical to an old class that I created and forgot about: GTFSCommon.  GJ, man.  GJ.
