//Description:
//      Contains definitions for UNI-AAL interface Indication (ind) and
//      Confirm (conf) primitives. Primitives are implemented as
//      OVOPS++ messenger classes according to Visitor pattern.
//      If primitive has parameters, access methods (set and get)
//      for those parameters are defined.
//      The class uaalUpInputs is a pure virtual base class for states
//      using Indication and Confirm primitives defined in this file.
