 * At times we have to do polling in javascript, that is have function run at a specified interval 
 * repeated times.  However, certain function polling will reduce battery life thus
 * each of those features should have its own user defined interval
 * that our js reads in and uses with of course conservative value used
 * is consumer has not set one or the user of this library has not set one.
 * 
 * Timeout only runs function twice not repeated times and thus we use
 * setInterval. This should correct problems with
