Cleaned up and make compareCandidates more user friendly with command line arguments and non-IFO specific variable names
Fix minor things in skygridsetup and testVectorMath
Remove useless functions in TwoSpect, fix useAVX flag, add print statement of usable SFTs in logfile
Many minor changes to improve TwoSpect

 - move print statements to functions
 - changed return 0's to return XLAL_SUCCESS
 - changed calcStddev(), calcHarmonicMean(), calcRms(), ks_test_exp() and kuipers_test_exp() to return INT4 with first argument the output
 - added printREAL4Vector2File()
 - change ihsfarstruct->ihsfar->data[0] initial and recalc FAR threshold to be -1
 - removed printUninitialized option
 - added input checks to some functions
 - added some function comments
 - changed some 'input' to 'params' for consistancy
 - removed calcMedian_ignoreZeros()
Converted the readInSFTs() function to use other functions and more consistent params usage
Removed useless code, added more input argument checks
Replace twospect_sin_cos...LUT() with CWFastMath function and remove unused twospect_sin_cos...LUT code
Add timing to testVectorMath
