First effort at search / replace unsigned with size_t.
Catch a few cases where "size_t long" was showing up as a type.
Cmake improvements
- Split setup of Boost and NetCDF into usmlBuildSetup.cmake
- Add config directory to CMake module path instead of copying into
  /use/shared/cmake directories.
- Create FindUSML.cmake routine for use my USML applications.
Corrected logic for wrapping data when database allows and added guards to prevent wrapping when database does not allow. This resolves issue #86.
Update install instructions to reflect improvements
in installation process.
Allow USML to work with the Boost 1.41 that comes with CentOS.
Use the progress_timer from Boost 1.41 instead of auto_cpu_timer from 1.57.
Merge branch 'master' into cmake_improvements

Clean Up of size_t everywhere.
Add boost-static to RPM instructions.

Search and replace all instances of unsigned with size_t.
-- Test by compiling under Linux 64, Win32, and Win64.
-- Win64 found the most errors because their "size_t" is not a "long".
-- Required modifying NetCDF-3 C++ interface to resolve issues on Win66.
Merge pull request #85 from campreilly/cmake_improvements

Cmake improvements tested by Ted Burns.
Fix errors in unsigned math for az-1.

data_grid derivative formula has been revertered to the original equation. data_grid_svp/bathy have had slight tweaks to code to be more visually easier to read. The derivative for the data_grid_bathy was missing divisor of the interval around the interpolation point. Cleaned up datagrid_test code.
Merged changes from origin/master to local/master.
Merge branch 'master' of ssh://github.com/campreilly/UnderSeaModelingLibrary into netcdf_wrapping
Completed testing for netcdf wrapping logic, resolving issue #87
	-Added two new tests, read_profile_test/nonglobal_database and read_bathy_test/nonglobal_database. These tests, are used to verify that the new logic for nonglobal database sets is working properly.
	-Corrected a min/max error in the longitude dimension with netcdf_bathy/profile.
Added support nc files for tests.
