This merge request adds the feature of passing a stopping frequency fEnd to the SpinTaylorTx wf approximants. The fEnd must be added as the FinalFreq entry of a LALDict structure.
It has been added the function XLALSimInspiralWaveformParamsLookupFinalFreq() to add fEnd to a LALDict structure (and its LookUp counterpart)
While the default behaviour of the XLALSimInspiralSpinTaylorDriver() is unaltered, the function now checks for an upper frequency value fRef, and if it is set to a positive value, the integration is stopped when it goes past it.
To ease the check of the functionality of the patch, the following script may help final_freq_test.py
