Python: need to determine how to handle paths

[elsevers]

Currently, the Python implementation requires that a script file using the eMach objects be located at a certain relative path (i.e. examples folder needs to be located in the python folder, it cannot be in python\eMach). This isn't going to be a workable solution for people who use eMach via a git submodule.

One solution would be to permanently alter the python path environmental variable, but this seems a bit heavy handed and would require a user to do this every time they move their project to a different location on their hard drive.

Is there a more moderate compromise here? In MATLAB we can add folders to that path that only persist their until we restart MATLAB. Can we do something similar in Python?
