Buttons problem

[stevestrong]

For your information,
I also needed in one project a button library and decided to use the button library you mentioned because it has callbacks for each event.
But it did not worked as I wanted to, in particular it had large time delay to detect a click event.
So I decided to make some changes to it.

The result is an improved version which not only that detects faster a click event, but also detects multiple consecutive clicks and presses (more than 3).
I posted the improved version here: https://github.com/TanPitch/ButtonKing/issues/6.
