/**
 * An animation parameter type. Stores an array of strings
 * representing the different states of a parameter, e.g.
 * "Idle", "Busy" etc. <p>
 * You need to specify a parameter type in order to get a parameter
 * to display on a timing diagram.<p>
 * Example code to add a parameter type from a user's
 * entity constructor is below.
 * <pre>
 *   String[] wstate = {"idle","busy"};
 *   add_param(new Anim_param( "State", 
 *                          Anim_param.STATE, 
 *                           new Param_type("wstate", wstate)
 *                           ));
 * <pre>
