Adding more details about Freehand function unit
Fixing the test of the freehand function unit
Adding more details about Freehand function unit
Adding unit tests for a number of compound filters. Currently valuees are simply duplicating what the filters gives as output, so not very trustworthy, but at least it will be an indicator of whether future refactoring change the DSP algorithm.

Adding (broken) unit tests for hilbert filters, so Tim can take a look
TTHilbert9: test now passes AudioSignalArray instead of AudioSignal to process method.  Will require a rebuild of the DSP library because of a tweak I made there to more intelligently initialize the TTAudioSignalArray when it is instantiated.
Hilbert filter unit tests now pass, but is it "expected" that real signal for Hilbert33 is a zero vector?
