//NOTE: This is only a DICTIONARY with MOST character to keycode bindings... it is NOT a working cs file
//ITS USEFUL: when you are reading in your control scheme from a file

//NOTE: some characters SHOULD map to multiple keycodes (but this is impossible)
//since this is a dictionary, only 1 character is bound to 1 keycode
//EX: * from the keyboard will be read the same as * from the keypad... because they produce the same character in a text file
