Cannot install shell_analysis_fenicsx package with current package/directory names

When trying to install pip install -e . I got the following error:

I believe this is because setup.py specifies a package name of shell_analysis_fenicsx (lowercase "x") but the directory containing the package files is currently called shell_analysis_fenicsX (capital X). I renamed shell_analysis_fenicsX to shell_analysis_fenicsx and was then able to successfully install the package.

Actually, I'll change my suggestion here. Various parts of the code assume that the module is called shell_analysis_fenicsX (with a capital X), so it's best to keep that convention. Thus, rather of renaming the directory as stated above, one can instead change the name of the module in setup.py from shell_analysis_fenicsx to shell_analysis_fenicsX.
