Made some changes that seem to work, how do I handle pull request?

Hi @boyan-soubachov, @bandwiches,

I made some changes in a cloned repo to the example.py and quite a few other files to run more examples, I added more useful data to current classes, added some comment throughout:
(1) It passes all the current tests

but
(2) I've added some new files and classes, used in the example.py file but I don't know how to create new tests for these
(3) I added the use of pandas in the example.py to store lots of data (like repeated streamer quotes) in dataframes, is that acceptable?
(4) Do I just submit a pull request for all the changes all at once or should it be done in smaller chunks? (never submitted a pull request before)

Thanks!
