  NGRule
  This class represents a rule inside the rule-model. A rule conceptually has:
  - a qualifier - aka lhs (the condition which must be true for the rule)
  - an action   - aka rhs (the "thing" which is performed when the rule is
                           triggered)
  - a priority  - to select a rule if multiple ones match
  
  String Representation:
    qualifer => action [; priority]
    *true*   => action
  
  Example:
    "(request.isXmlRpcRequest = YES) => dispatcher = XmlRpc ;0"
