Start of main program file, gamechanger.py, as well as some sample data

@sunhwap Hey! So, I started a script for the main part of our program. Mostly it's pseudocode, as well as some hard-coded elements to get us started in terms of thinking about how this program will work. It includes dictionaries with most of the data we needed outside of the tweets (namely school data, schedule/tv data); while gathered from the ESPN API and other sources, it's just hard coded at this point (which might be the most we do for this project).

At this point it starts to address issues #4 and #5, but I don't know that we want to actually close them yet? I'll go ahead and reference them here, but we can reopen if needed. It also starts to address the need to accumulate mentions of each game, but still needs a lot of work. You can merge, or just wait if you'd like!

(I also just created a really short sample text file with play data, just to test out the code without dealing with the big dataset)

Fixes #4 
Fixes #5
