+ * Collapser:  Takes two elements and creates a visual "expando:" clicking on one element expands/collapses the other.
+ * Required properties:
+ *              clicker: The element that will be clicked on.
+ *              content: The element that will expand or collapse as the clicker is clicked on.
+ * Optional properties:
+ *              isCollapsed: Is the content collapsed.  Set to true on serialization (or initialization) to start content in collapsed state.
+ *                      Can be manually set as well.
+ *              collapsibleClass: The CSS class to apply to the content and the clicker when collapsed.  Defaults to "collapsible-collapsed".
+ *              isAnimated: Set to true to apply a transition to expand/collapse (defaults to false).
+ *              transitionClass: If isAnimated is set to true, the component will apply transitionClass to the content during the 
+ *                      collapse process.  You can then define transitionClass in your style sheet with the desired CSS transitions.
+ *                      Defaults to "collapsible-transition".
+ *              contentHeight: If both isAnimated and isCollapsedAtStart are set to true, set contentHeight to the height of the content 
+ *                      (in pixels, but without the "px") when not collapsed.  If this value is not set, the first time the content is expanded 
+ *                      the transition will not work. Subsequent collapses (and expansions) will transition as expected.
+ *              isLabelClickable: Boolean that indicates whether or not the clicker should have listener events. Defaults to true; set to 
+ *                      false for collapsers that will only be operated remotely.
+ *              toggle(): Manually toggle the expand/collapse of the content.
+ *
