Add a sort method to FixedFloatArray
Add some tests for FFA.sort
Fix a subtle bug where sort would not work correctly on systems where sizeof(INTVAL) != sizeof(FLOATVAL)
Hopefully fix FFA.sort() bug, caused by my questionable casting. @nwellnhof++ #929
Eschew the use of == on FLOATVALs, @pmichaud++
