buttonAPI

--[[

    (C) Button API made by (C) LeV__oid
    This ButtonAPI is used to make the creation of buttons easier

    Loading this API is easily done by writing "os.loadAPI("buttonAPI")" at the top of your script.
    From there on you will be able to call every function like so:
    (Example:)
    buttonAPI.mkBtn(5, 5, 13, 13, colors.lime, "Test")

    help() - Prints a list of all available functions this API adds.
    (Example:)
    buttonAPI.help()

    mkBtn(xmin, ymin, xmax, ymax, color, name) - Draws a Button to the screen starting at P1(xmin, ymin) and going to P2(xmax, ymax). It will have the specified color and Text.
    (Example:)
    buttonAPI.mkBtn(5, 5, 13, 13, colors.lime, "Test")

    Soon to be added:
    I am planning on adding a feature that will let you make sliders (for example: for the rod insertion of big reactors) and also filling bars/diagrams (for example: for showing how much RF/EU/Whatever is stored in whatever container)
    I am also planning on making this a standalone API because currently you will still have to set your mouseclick detection manually

    Thank you for trying out my API.
    Have fun!
