Menu command to run GSAS-II scripts #311
Description
It would be nice to have a mechanism where one could launch a GSASIIscriptable script from the GUI. This would allow users to create their own extended functionality and integrate that into GSAS-II operation.
I am imagining that one could pass in a .gpx file either as a command-line argument or via an environment variable. The file would need to be saved before calling the script and reloaded afterwards.
The other thing that I am not sure how to handle is making sure the usual import statements would still work so that the script can be launched either directly from Python or from inside GSAS-II.
Another thought here is that one could have a mechanism to detect such scripts and then place commands into a the menu as a way to customize GSAS-II with external scripts.
