Allow single quotes to form a docblock for python

[MasterOdin]

The current version will fail if a student uses single quote docblocks, and then a single quote within that docblock as the parser does not recognize that as a multiline comment that should be ignored when parsing.

An example of this would be:

'''
Some test comment that I'd like to see pass
'''
first = input("Enter the first number: ")
print(first)
if float(first) < 5:
    print('Below five')
else:
    print('Above file')

where running:
count --language python token If test.py should output 1 (currently outputs 0)
