gstlal-calibration/tests/check_calibration:  Added GPS start time to name of files in pcal-to-darm plotting script.

gstlal-calibration:  Added debugging element splitcounter for printing buffer timestamps and offsets to screen and file.

gstlal-calibration:  Example in tests/check_calibration/Makefile for using transfer function plotting script.

gstlal-calibration:  New plotting script in tests/check_calibration/plot_transfer_function.py to plot transfer functions.

lal_transferfunction:  added event() function back in to get best possible transfer functions at EOS.

gstlal-calibration:  Improved methods for doing noise subtraction multiple times using different witnesses in series.

- test_commpn.py:  Seeking pipeline seems to work now.
- pcal-to-darm plotting script:  now works in new setup.
- gstlal_compute_strain: removed stray dq_epics variables

gstlal-calibration:  Using Makefile to generate directories with filters when needed, but these directories are in .gitignore, so they will not be part of the gstlal repo.

gstlal-calibration:  removed git submodules with git-svn directories, which did not work the way we had hoped.

gstlal_compute_strain:  Split the PUM and UIM stages of the actuation and calculate kappa_PUM and kappa_UIM separately and apply them.

gstlal-calibration:  Added git submodules with calibration filters from the calibration SVN. The submodules were made using git-svn.

gstlal_compute_strain:  pipeline searches for filters file given only file name in config file.  Order of preference for which filters to use is:
1) Filters from the calibration SVN (that is, those found in /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/*/GDSFilters/)
2) Filters in the user's home directory in a subdirectory called GDSFilters
3) Filters in the user's home directory in any subdirectory

- tests/check_calibration:  Caitlin Rose's Automated testing scripts and Makefiles for doing calibration tests.
- gstlal_compute_strain:  Don't demodulate the pcal channel again to compute SRC detuning if re-using the ~30 Hz pcal line
- lal_transferfunction:  1. Bug fixes for median of transfer functions.  2. Option to compute first transfer function asap at start of stream.  3. Use GPS time to decide when to update transfer functions so that output becomes independent of start time asap.
- tests/check_calibration:  Added plotting script and Makefile example for plotting time series of \DeltaL / pcal at calibration line frequencies.
- config_files:  Example config file for offline calibration with noise subtraction.

gstlal-calibration:  new element lal_dqtukey that reads in a bit vector and outputs a stream that makes smooth transitions between zero and one based on the bit vector.
