Module: slider
The Slider component is a UI control that enables the user to adjust
values in a finite range along one or two axes. Typically, the Slider
control is used in a web application as a rich, visual replacement
for an input box that takes a number as input. The Slider control can
also easily accommodate a second dimension, providing x,y output for
a selection point chosen from a rectangular region.
