The button is a sprite which makes it very easy to use many times in the program and easy to customize.
#load_image is used in most pygame programs for loading images

image.set_colorkey(colorkey, RLEACCEL)
return image, image.get_rect()

position of topleft corner. Method pressed() returns
a boolean and should be called inside the input loop."""
