The directory layout created by pip install is wrong.

When using pip install ExcelFormulaParser, this puts the directories Models and Tests directly under site-packages, without a directory ExcelFormulaParser inbetween.

And the import statements inside the Models directory must be relative.

This is a show-stopper barrier to using this library in a team if I can't pip install it in a venv.

This issue could be fixed within the setup.py module and some of the ways the init.py files are laid out. Just to point you guys in the right direction. I may not have time to get around to fixing this for a bit as my job keeps me very busy. Thank you guys for using this tool or at least checking it out. I'll keep you posted if I can get to this soon.
