-// Call ToggleButton to wire an HTML button (typically an <img> tag) to a JS callback
-// when you want the button pressed state to be tied to a Ginebra snippets 
-// visible attribute.
-// 
-//
-// Params:
-//   id - the id of the button.  Ex:  <img id="buttonId" .../>
-//   snippetId - the id of the ginebra snippet to which the button state should be tied
-//   upImg - the path to the "up" image for the button.
-//   downImg - the path to the "down" image for the button.
-//   disabledImg - the path to the "disabled" image for the button.
-//   handler - the javascript callback to be called when triggered
-//   triggerOnMouseUp- if true the handler will be called on mouse-up, defaults to true.
-//   triggerOnMouseDown - if true the handler will be called on mouse-down, defaults to false.
-//   triggerOnMouseOut - if true the handler will be called on mouse-out, defaults to false.
