Start work on collecting envionmental data for Florida Straits study.
Update the pictures to include sediment boundary.
Create reflect_loss_florida test.
Build matlab scripts to debug problem with bottom loss model.
Includes a matlab version of the Rayleigh reflection loss,
and Jensen, Kuperman, et. al. examples for BL vs. changes in
bottom parameters (Fig 1.23) and BL vs. mnemonic bottom type
(silt, clay, etc., Fig 1.24).
Add new bottom loss picture to report.
Add README to Florida Straits study.
Bottom loss model testing for Florida Straits.
* The reflect_loss_rayleigh model had a bug where speed_shear was
  not being scaled correctly.  Now the results of the
  plot_rayleigh_sediments match Fig 1.24 in Jensen, Kuperman, et. al.
* Simplified the conversion from dB/wavelength to the
  loss tangent by defining ATT_CONVERT constant.
* The input parameters for reflect_loss_florida were not
  in the correct units for the reflect_loss_rayleigh model.
Store results of improved reflect_loss_florida test.
Merge branch 'florida_straits' of /media/sf_usml-git into florida_straits
Ingest environmental data for Florida Straits study.
Add ascii_arc_bathy to usml::ocean package.
Add a test routine for this to boundary_test.
Add a special reflection loss model for CALOPS area.
  - Shallower than 236 m is sand, deeper is limestone.
Allow reflect_loss_calops to province the bottom
using the bathymetry.
Do some cleanup by replacing relect_loss_calops with
relect_loss_florida.
Update report
Making progress on modeling CALOPS Run1A area.
- ascii_arc_bathy now seems to be working.
- ascii_profile_factory still needs work.
- create main routine = calops_s_run1a.
- get main routine to compute and store wavefronts
  without TL.
Make a more consistant naming convention.
Save work to date.
More name clean-up.
Update plotting routines.
Update the Matlab plotting routines.
Note that ASCII must be read backwards in latitude
to make the first point into the south-west corner.
