   *             local images are to be used, LocalUrl should be used in those specific places
   *  this.LocalUrl - the host and path on the local server where the .js file is found.
   *                This is used just to find the local stylesheet and possibly images
   *  this.XmlApi - identifies the xmlapi host and several search params to which the
   *                other query params will be added
   *  this.UICode - identifies the uicode of the acct if relevant. This is needed to 
   *                properly construct the links to "Read on Safari".
