out_folder in defaultDict is prone to errors

[reneSchm]

Bug description

The path is set via splitting the current file directory at "memilio", which usually works as intended, i.e. setting the out_folder to "memilio/data". However, if there is another directory called memilio, e.g. "Projects/memilio/memilio" or if the git repo was renamed, out_folder is set to "memilio/../data" or "memilio/pycode/memilio-epidata/memilio/epidata", respectively.

Version

Windows

To reproduce

1. Either

• clone memilio into a directory, which already contains memilio in its path.
• rename the memilio project directory

2. Check defultDict["out_folder"]

Trying to use downloaded files from epidata with python examples or some simulations will also fail.

Relevant log output

Add any relevant information, e.g. used compiler, screenshots.

• Attached labels, especially loc:: or model:: labels.

A functionality similar to mio::base_dir would be nice.
