guiAPI

--GUI API by neonerZ v1.0
--http://youtube.com/neonerz
--

-- use os.loadAPI("guiAPI") (or whatever you named it) to include this
-- API in your script. To call a function, you'd use guiAPI.function(vairables)
-- If you named this script somthing other than guiAPI, adjust the above command accordingly
-- example usage: register a button
-- guiAPI.setTable("button1", "Button Name", 3, 4, 10, 3, 4000, 4001, colors.blue, colors.white)
-- This script must be in the same directory as the script calling it
-- you can also add this to your turtles rom/api folder to use it like a standard computercraft API
