Devlog #3

I added 2 new features and wrote my readme.

Feature #1: Orange Keys
By checking off this check-box the white keys in the piano simply become orange. I did this by creating new css styling for the orange keys, created a check-box using html, and then used a event listener in JS to switch the white keys css styling with the orange keys.

Feature #2: Trial Song
For this feature I basically created a box above the piano with the notes for the song: Mary had a little lamb. Instead of using musical notes I used the letters on the piano keys so everyone can easily play it.
