Tests are left commented for now in favour of getting the new code to 
the master.

I cleaned up the code in the FormChecker class mainly. I also commented out some print statements that were not necessary for me. The cleaning up mainly included making code more readable, for which I also made one additional function.

I included documentation for the FormChecker class. As well as changing the class to correspond with our way of code-formatting

I added documentation to the various functions in the FormChecker class. I also discovered an bug case which still needs to be fixed.

Renamed 'Irregular Verbs.csv' to better follow naming conventions, moved it to resources folder and adapted call to it accordingly

Statements with multiple of these (el)if statements now use the or 
operator. Additionally, added spaces after commas where still absent.

Fixed bug where the splash remained as an overlay, rendering the program unsusable. Cause was an uncommented line of code, that should have terminated the splash window

This allows for not setting the icon in linux, circumventing the problem 
of tkinter on linux not being able to handle .ico icons.

This is the actual finished version, something had gone wrong with the git commands. The FormChecker class is now finished and integrated

We finished the FormChecker class by adding the conjugations of regular verbs as a form mistake possibility. We also ran various test cases to ensure that it works. Lastly we integrated this in the Needleman-Wunsch class

Started on fixing the form mistake finder, because it does not work now. Stopped half way so the code is not runnable now.
