General Improvements

This update primarily was just me recoding a lot of the architecture I originally made for this program for more efficient reiterations and updates. (As well as general performance being enhanced) Other than that I removed the time signiture feature as it didn't really work as intended and it just didn't seem all that worth it, so in place of that I added a slider that allows the user to choose how many notes they want to generate from 4 to 12!

I hope the program is useful so far!
