Catching Error messages from Button-function

[roehligas]

Hi,

just a quick recommendation to everyone who's struggling with errors on their scripts that are not run directly instead of through the PythonConsole...

I setup all my scripts so that there's a wrapping-function in a try/except block that launches the actual code.

If the code fails, an Errorlog file is created and stored in the corresponding script folder.

Feel free to enhance it, I'm not entirely happy with the level of detail of the error messages...

"""
This is the Wrapper-script for the Function.

It stores the errorlog as a text file if the execution is crashing.
