Added a Python script to compare the original SD1 tone circuit to the digitized version
Starting SD1 Tone filter, as an IIR filter
Python interface
Adding tests to ensure SD1 tone implementation is OK (it is not)
Added new tests and fixed implementation. Still some issues though.
Filters coefficients seems to be OK, but implementation diverges??? Is it related to the test issues?
Fixing a damn big issue (reset was supposed to be called by hand before each process call)
Fixing FFT free calls
Fixing a bunch of signed/unsigned issues + some out of vector reads
Windows fix for EQ tests
Oops, errors with order type
Fixed tests after reset debacle
Trying to stabilize the Python interface
Adding the example file that shows an error in the analog filter transform (analog unstable)
Perhaps the proper way of defining the SD1 tone. Need to check the equations again for a sign mismatch.

amp check is OK on Linux but not on Windows -> float representation issue ??
Merge branch 'feature/SD1Tone' into develop
Added needed methods to use *PointerFilter as sources and sinks in audio plugins
Fixing SD1 tone tests for 10kHz
