Location of results folder depends on trailing slash

[nachtm]

With the edits from #13, we can run the project. It mostly works, but is a little unstable. If you run it like so:

python3 -m src.mqm inputFolder=/Absolute/path/to/parent/shallow/folder it runs fine.

However, if you run it like python3 -m src.mqm inputFolder=/Absolute/path/to/parent/shallow/folder/ it creates the results folder inside of shallow/folder/ and tries to read from it, failing to do so and throwing an error:

Traceback (most recent call last):

IndexError: list index out of range

We should always create the results folder outside of the folder from which we're reading.

Beware: if you have a trailing forward slash in your --folderPath arg, it will create a results folder in your path, which will then break your next run unless you delete it!
