Installing as administrator and running as regular user raises `PermissionError`.

[rodrigogiraoserrao]

After using setup.py to install pynapl, with administrator permissions, in a Windows 10 system, pynapl is installed in the standard location for Python modules, in a “protected” folder.

Hence, when a regular user tries to start pynapl, it fails, because Python will try to write the WinPort.dyalog file in a protected location.

Here's the traceback we get after a script tries to import pynapl and run the APL function in APL.py:

  File "C:\Users\rodri\Documents\Dyalog\pynapl\pynapl\demos\game_of_life\game_of_life.py", line 5, in <module>
    apl = APL.APL()

The original code comments that using the auxiliary WinPort.dyalog file ”is dumb, but works, but is still dumb”.

Either try to write the WinPort.dyalog file in a location appropriate for temp files, or try to remove this “hack” altogether (no idea how!).
