SETSTATE  Set the algorithm state

      B=SETSTATE(A,STATE)

 INPUT
   A           SDALG algorithm
   STATE       String state
    'trained'    algorithm is trained and ready to execute

 OUTPUT
   B         SDALG algorithm with changed state

 DESCRIPTION
 SETSTATE changes the algorithm state. It is used at the end of
 the training section where the untrained algorithm becomes trained.
