** Title: Icon Rollover JavaScript Library        **
** Date: July 26, 2000                            **
** Authors: Pangaea Systems Inc. and Kofi Garbrah **
** Purpose: Causes an icon to change into a       **
**          different icon when the user touches  **
**          it and change back when the user is   **
**          not touching it. This can be used to  **
**          produce various animated effects.     **
**                                                **
