    PetscOptionsBegin - Begins a set of queries on the options database that are related and should be

   Synopsis: PetscErrorCode PetscOptionsBegin(MPI_Comm comm,const char prefix[],const char title[],const char mansec[])

    Collective on MPI_Comm

  Input Parameters:
+   comm - communicator that shares GUI
.   prefix - options prefix for all options displayed on window
.   title - short descriptive text, for example "Krylov Solver Options"
-   mansec - section of manual pages for options, for example KSP

  Level: intermediate

  Notes: Needs to be ended by a call the PetscOptionsEnd()

         Can add subheadings with PetscOptionsHead()

     PetscOptionsTail - Ends a section of options begun with PetscOptionsHead()
            See, for example, KSPSetFromOptions_GMRES().

   Collective on the communicator passed in PetscOptionsBegin()

   Synopsis: PetscErrorCode PetscOptionsTail(void)

  Level: intermediate

   Notes: Must be between a PetscOptionsBegin() and a PetscOptionsEnd()

          Must be preceded by a call to PetscOptionsHead() in the same function.

          This needs to be used only if the code below PetscOptionsTail() can be run ONLY once.
      See, for example, PCSetFromOptions_Composite(). This is a return(0) in it for early exit
      from the function.

          This is only for use with the PETSc options GUI; which does not currently exist.
