  /////////////////////////////////////////////
  // Control w.r.t Rabin specifications
  //
  // The A-B-Machine is a machine that can run process A (event a) or process B (event b). 
  // Per operation, the machine may succeed (event c) of fail (event d). However, it is 
  // guaranteed to eventually suceed when running the same process over and over again.
  // We have three variations:
  //
  // 1: the std case 
  // 2: process B exhausts the machine: it will succeed in process B once and then
  //    fail on further processes B until process A was run.
  // 3: process B breaks the machine: it will succeed in process B once and
  //    then fail in any further processes
  //
  // We synthesise controllers for 3 variant specifications
  //
  // 1. Alternate in successfully processing A and B
  // 2. Keep on eventually succeeding in some process
  // 3. Run optionally process A, eventually turn to B until success, repeat
