 *
 *  This file contains the implementation of the PackageConfiguration
 *  Visitor class PlanUpdater which derives from PCVisitorBase and attempts
 *  to update the location fields in the received DeploymentPlan to reflect
 *  the locations of the implementation artifacts as outlined in the
 *  PackageConfiguration which are downloadable via HTTP. Each Visit
 *  function focuses on the functionality necessary to process the
 *  PackageConfiguration element which is passed to it as an argument
 *  and on dispatching the next sequence of calls in the correct order!
