;This program is a simple bot for a twitch stream. It will send a message that you give it to the twitch chat if the chat is positioned correctly (The chatbox must have a position in it that is 1160X 615Y) every 20 minutes (approx.)
;Usage: Begin the program follow the prompts and the first thing you should do is select "edit messages" because the program, by default, has no messages in it and won't print anything unless it actually has a message to print
;Notes: The program has space for 5 messages by default. In order to increase it edit the number on line 13
