update to motmsc/nlc.m that seems to fix non-linearity problems
with the new code.  This and DClevel_model.m should move to source
after some more testing.

snapshot of motmsc/ccast_mean.m and idps_mean.m, used for the 3 Apr 2014
blog report "three-day nonlinearity comparison", added modmsc/interp_test.m,
used for the 24 Mar 2014 blog post "resampling residuals", and moved the new
versions of nlc.m and DClevel_model.m to source.
Major updates to motmsc including a new ILS function, ILS tests, and
tests of sinc vs psinc as presented at the May 2014 JPSS science team
meeting.  Added a short project description to the top level README,
and fixed an uninitialized variable in checkRDR.
switch defaults to periodic sinc ILS, wrapping at the sensor grid.

  newILS     - new ILS function, defaults to psinc
  mkSRFtab   - build SRF matrix tables for interpolation
  mkSRFrun   - example using mkSRFtab with typical values
updated ccast_main, _hires1, and _hires2 to use SRF files tabulated
with new ILS function.  Consolidated cluster (slurm) scripts in the
"runs" directory.
major updates to the ILS calc, documentation, and preprocessing

 - revised normalization in newILS.m, as suggested by Yong Han

 - added motmsc/calmain_c1.m and calmain_c2.m, two variations on
   the reference calibration equation

 - added doc/ccast_eqns, Latex slides including the ILS integral,
   reference calibration equation, and variations c1 and c2

 - updated the ccast preprocessing, replacing the old do_rdr2mat
   with ccast_prepro.m and an sbatch script ccast_prepro.sh
major reorganization and simplification of directories and paths.
the test directory motmsc is not on any regular production paths,
and the davet and source directories are now disjoint.  the README
files were updated to reflect this
major update of documentation.  The doc directory now includes

  doc/ccast_intro.pdf  - an overview of design and project status
  doc/ccast_eqns.pdf   - intro to the ILS and calibration equations
  doc/matlab_sdr.txt   - the matlab SDR format field definitions
  doc/finterp.pdf      - some notes on Fourier interpolation
  doc/status.txt       - ccast status report as of 12 Dec 2013

In addition, the main README, source/README, and motmsc/README files
have all been updated.
rewrote ccast/README to include installation and testing notes and
moved most of the more general info from there to doc/ccast_info.pdf.
Added demo/ccast_main.m and demo/ccast_prepro.m with paths set to
match test paths in the demo directory.
minor documentation updates after successful install tests
updates to ccast_intro and added high res demo
added the function scantail to rdr2sdr to shift the scan tails so
output starts at FOR 1.  updated rdr2sdr, scanorder, mkSRFtab, and
test functions cut_tes1 and ils_test 3 in motmsc.  the scantail mod
is still being tested.
the main processing steps in rdr2sdr are now:

  - load the matlab RDR data
  - process sci and eng packets
  - order and validate igm data
  - group igm data into scans
  - take igms to count spectra
  - calculate moving averages
  - L1a to L1b calibration

updated scanorder and igm2spec to work in this context and
fixed an oversight in scantail to trim tailing partial scans
modified rdr2sdr to trim SDR output to user grid plus two guard
channels at the edges of each band, dropped unused output params,
and updated documentation to match recent mods
updated scantail to check tail array channel set sizes, added
motmsc/asl for the IDPS SDR readers and SDR to RTP function, and
cleaned up motmsc/zold
