-Bug fix to all output requiring AE for dates after the end of the AE record.
-Removed environment variable dependence from AACGM.
An overhaul of the AACGM has been done in order to remove all environment variable dependence. The user only needs to modify to config.ini file in the root directory for the AACGM to work properly.
Fixed a bug with AACGM running on Unix machines.
Some users experienced issues with loading the AACGM shared library when the path was a string. It has been forced to a char array to fix this. We now capture the users working directory at the start of a run and CD back to that directory on completion.
