Check for TODO and commented out code

Check that looks for existing TODO's and commented out code in a repo

Only checks .py and .md files for TODOs, and only .py for commented out code

TODO's are considered:

• todo
• TODO
• to-do
• FIXME
• fix-me
• fixme
• fix me
• to do
• FIX ME
• TO DO
• XXX
• xxx
• FILLME
• fillme

Commented out code is any single comment in a .py file that could be considered code E.x.:

for item in list:
    #print(item)
    otherlist.append(item)

Where the print statement would be considered commented out code

E.x.:

for item in list:
    # Add item to the other list
    otherlist.append(item)

Where the comment here is not considered commented out code
