      7:      PetscTextBelt - Sends an SMS to an American/Canadian phone number

      9:    Not collective, only the first process in MPI_Comm does anything

     11:    Input Parameters:
     12: +  comm - the MPI communicator
     13: .  number - the 10 digit telephone number
     14: -  message - the message

     16:    Output Parameter:
     17: .   flg - PETSC_TRUE if the text was sent

     19:    Level: intermediate

     21:    Notes: TextBelt is run for testing purposes only, please do not use this feature often

     23:    Developer Notes:  I do not know how to make the buff[] long enough to receive the "success" string but short enough that the code does not hang
     24:        waiting for part of the message to arrive that does not exist, hence the success flg may be improperly set to false even
     25:        though the message was delivered.
