Previously, the program only scanned whether the current line contained a quote. I modified it so that it sets a bool to true once a quote has been reached. Once it reaches a line with nothing but a newline, it sets the bool back to false.

This update makes logical sense. Testing should be fairly easy. I'll give it a shot before I start running the new code.
