/** The FragmentController sends bunches of jobs to a FragmentScheduler,

 * While the FragmentScheduler and FragmentWorker rather act on their own
 * this is the piece to implant into the user software to allow for
 * communication with the Server/Worker duo to perform the calculation
 * of the fragments on distant computers.
