Script: OptionChannelReveal
Author: Andy Badke
Description: This class allows a set of trigger objects to hide or show a set of associated objects.
In this case two arrays are passed in, one of objects and one of associate objects.
Each object is paired to its associate object in the order they appear in the array, and clicking the element will toggle
its state and toggle the display style of its associate.
