Removed some extra files from the test project that are only good for my useage
Forgot to remove a redundant loop -_-

Also migrated some utility functions to SignalHelpers.java to get some crap out of the "main" that's too cluttered as it is.
Revert private status on filterSignalData back to public as I can't test it very well that way (well unless I want to use reflection and fuck that :/)
Refactorings:

--Moved most of the signal processing methods out of the main activity and into SignalData.java so it doesn't become a bloated mess with additional code for new features and such.

--Moved some of the "helper methods" out of the utility class and into SignalData.java

--Using an enum instead of a bunch of constants for signal information lookup indices.
