    PetscOptionsBegin - Begins a set of queries on the options database that are related and should be
     displayed on the same window of a GUI that allows the user to set the options interactively.

   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()
