Removed decprecated function accessors to the wavefronts surface/bottom matrices.
Changed function name to standard form from wave_queue_netcdf and proploss.
Updated accessors to the attenuation/path_length matrices to now follow the usml format.
Create new release notes for 0.4.1 and 1.0.0 versions.
Removed debug statements that were no longer needed.
Many instances of debug code had been added to supplement debugging of older issues. Once the issues were resolved the debug code was kept in the event that it was needed again. Now with the clean up of the release 1.0 underway, many of these old debug codes have been removed since they are no longer needed.
Since attentuation and path_length are public member variables in the header wave_front.h, accessors are not needed.
Removed missed include statement on ublas_special.h
Merge branch 'master' of github.com:campreilly/UnderSeaModelingLibrary
Update USML install instructions
-- Update version numbers in Test section
-- Add description of relationship between CentOS and Red Hat.
-- Add discussion of -O0 problems with Boost.
Convert all #include guards to #pragma once statements
  -- Required small change in most USML header files.
  -- Recompile everything in release mode.
  -- Re-ran usml_test executable.
  -- Closes #77.
Resolved Issue #80.
The error that valgrind was referring to was the values of dy0, dy1, dy2, dy3. Setting these to an initial value of zero resolved the valgrind warnings and the SIGFPE errors.
Merge branch 'master' of ssh://github.com/campreilly/UnderSeaModelingLibrary
Removed debug code and corrected write_netcdf in data_grid.h.
Found many instances of debug code that were commented out, but not in ifdef statements. Should take a long pass over code to make sure there are no other instances of these commented out debug code.
write_netcdf function of data_grid was not functioning properly. NcDim was not working as intended for n-dimensional cases and NcVar varname needed to not have a temporary when being passed in.
Changed the derivative calculation in pchip to resolve issue #84.
Merge remote-tracking branch 'origin/master' into v0.5.11-branch
