Start work on speed comparison with CASS.
- Built CASS runstreams to compute compute transmission
  loss for 1, 10, 20, 30, ..., 100 targets.
- Implement as a ring of receivers at 100 km from source.
- Use Matlab to create images of CASS bathymetry.
- Get image of equivalent ETOPO1 bathymetry from NGDC.
Convert CASS speed results into a spreadsheet.
cmp_speed update
- std14bathy.m now creates CDL file for import into netCDF
Added destructor to free up the memory from the vector of
reflect_loss_rayleigh pointers.
Merge branch 'development0.03' of https://github.com/campreilly/UnderSeaModelingLibrary.git into wave_front_edges
-Added debug ifdefs to reflect_loss_netcdf.
-Adjusted the tests in etopo boundary to check for a value less than,
as opposed to a CHECK_CLOSE.
-Updated logic in data_grid.h for _edge_limit to correctly account for
axes that are positive/negative increments.
-Added line to state that reflect_loss_netcdf_test completed and passed.
