Added comments and changed s registers to t registers.
Fixed the ascii art for mars
Added a trap handler so that backspace could work. Should probably
make it so that I can differentiate between a backspace trap and some
other kind of trap.
mars terminal has infinite columns so no need to calculate number of blank
lines.
Created a manual parser for the add command
Parser is now able to tell which command was typed in. Still need
to parse the arguments.
WIP on parser
Created a method for converting ascii integers to integers.
Added more info to the README about the velocity commands.
Parser works for both add commands.
Play note being parsed correctly. Added an extra file that will
handle the playing of midi. Currently have play_note function I was
going to test play_note's arg parsing with.
save and load now extracting the filename argument.
Parsing is done. Calling a bunch of placeholder functions that group
members need to fill in.
Fixed a minor bug in the play_note function.
