Drop extra setting of CMAKE_INSTALL_RPATH
Removed explicit optimization for debug builds.
Addressed issues related to running large file tests on machines < 4GB memory.  Updated messages to indicate what the problem was specifically, so that I don't spend another day somewhere down the road figuring out the problem yet again.
Cleaned out old Doxyfile templates that aren't needed yet/any longer.
They will eventually be recreated but not for a while. Also, modified
the install documentation to remove references to 'ed/local'.
Removed calls to process Doxygen templates that no longer exist.
Modified comment to adhere to doxygen format.
Added a new .gitignore specific to include/.
Added netcdf_meta.h to user documentation generated by doxygen.
