gstlal_compute_strain:  Added more flexibility to sample rates, etc., for various witness channels in the noise subtraction.

gstlal_compute_strain:  A couple small fixes so that it runs on shared memory after all the recent upgrades.

lal_trackfrequency:  fixed bug that occasionally causes code to get stuck in a while loop.

lal_transferfunction:  Added ability to notch out selected frequencies to avoid effects of loud lines in h(t) that are not in witnesses.

gstlal_compute_strain:  Wait for good h(t) before computing transfer functions between it and witness channels

gstlal_compute_strain:  added ability to process witness channels separately for noise subtraction, if desired.

lal_transferfunction:  Another small bug fix related to changing the resampling of the transfer functions.

gstlal_compute_strain:  Simplified removal of pcal lines. Also slightly simplified calculation of kappas.

lal_transferfunction:  Apply resampling and smoothing of transfer functions before matrix manipulations and before making FIR filters.

lal_transferfunction:  Perform checks on FFTs before computing transfer functions, to minimize loss of calculated stuff.

gstlal_compute_strain:  Simplified adders in state vector calculation. Edited --help output. Corrected ESD line removal.

gstlal-calibration:  New pipeline gstlal_compute_kappas which only computes the kappas (much cheaper than computing h(t)). It can also apply a filter to DARM_ERR to simulate the effect of time-dependent correction factors (\kappa_tst, \kappa_pu, \kappa_c, f_cc, f_s, Q), so that tests can be done quickly.

gstlal_compute_strain:  added options use either kappa_tst or kappa_pu to compute actuation time delay, instead of handling the timing of the actuation stages individually.

New cmath element lpshiftfreq that reads in a complex stream and multiplies the phase by a constant without affecting the magnitude. This can be useful when a function whose phase is proportional to frequency has a known value at a particular frequency, and the user wishes to evaluate it at a different frequency.

 - bug fixes in lal_adaptivefirfilt
 - Implemented lal_adaptivefirfilt to correct for f_s and Q time-dependence
 - Added options to correct for complex kappas
 - Added EPICS bits to calib state vector

gstlal-calibration:  New element lal_adaptivefirfilt that allows constrution of a time-dependent FIR filter with zeros, poles, gain, and a time advance/delay. For details, type gst-inspect-1.0 lal_adaptivefirfilt.

gstlal_compute_strain:  Modified smoothing of f_s and Q to produce better results. Began updating CALIB_STATE_VECTOR for O3.

lal_lpfilter:  new element that takes complex input representing amplitude and phase error of a signal at a particular frequency and computes a linear-phase FIR filter to correct this error.
