/**
 * The RuleCollection class allows a "Rule Group" to be specified.
 * Rule Groups are combinations of individual Rule objects.
 * 
 * Rules are combined to form RuleCollection objects using 
 * the "and" operators. 
 *  
 *  The current XML specification of this would be:
 * <Rule name="uniqueID"> 
 *      <Property key="WifiRule">UMTS</Property>      
 *      <Property key="PowerRule">true</Property>
 *      <Property key="PowerLevel">50</Property>
