 *         class to store connection information for Gateways this will be the
 *         data component of a MRL_URI_KEY since there are so many connection
 *         types and connection protocols on top of those types we will make a
 *         data class which has members which are common to all - then a HashMap
 *         of properties for specific elements
 * 
 *         future data might include session info, session time outs, heartbeat
 *         details, etc
 * 
 *         this will contain all serializable contextual data regarding the
 *         connection without containing the connection itself
