compoundPhaseSignalToNoise
This calculates the signal to noise ratio (short/long) in the time window described by the offsets around the given phases and passes if the ratio is less than the given ratio. See the documentation for the TauP Toolkit, http://www.seis.sc.edu/TauP for the phase naming convention. SOD uses the TauP Toolkit internally.
