/*
 * History Class that provides history, history data, and bookmarking for DHTML and Ajax applications.
 * A generic function is available on base of the 'real simple history' (Brian Dillard, Brad Neuberg)
 * adapted and streamlined/rewritten for the mootools frame work.
 * The revised class DhtmlHistory is named JRCmsRsh in accordance with the naming convention of
 * the JRCms Frame and comes with an additional definition of a source pool which is used by the history
 * for decoding/encoding of history entries.
 *
 * Conventions:
 * 1) we need the provided "blank.html* file for IE
 * 2) the JRCmsRshSource has to be instantiated as jrCmsRshSource first
 * 3) the JRCmsRsh shall be instantiated as jrCmsRsh while the DOM is finally loaded
 *
 * @package rsh: real simple ajax history
