The Canadian High Arctic Ionospheric Network

* Fixed an issue with the magnetic coordinate outputs. When using the ‘map’ keyword, the magnetic coordinate output matrix matches the density/NmF2 etc output matrices. * Added the option to update the local database file from the ECHAIM website. The user may choose to not update, update if a newer database is available, or to force an update. * Added an installation test script. The user can run this script after installing the model and test the output against a provided ‘expected output’ text file to ensure all pieces of the model is installed and working properly. * The AACGM components of the model have been updated to version 2.5. This includes the AACGM functions and the coefficients. * General typo fixes in comments and instructions.
