    Synopsis:
    #include <petscoptions.h>
    PetscErrorCode PetscOptionsBegin(MPI_Comm comm,const char prefix[],const char title[],const char mansec[])

    Collective

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

    Level: intermediate

    Notes:
    This is a macro that handles its own error checking, it does not return an error code.

    The set of queries needs to be ended by a call to `PetscOptionsEnd()`.

    One can add subheadings with `PetscOptionsHeadBegin()`.

    Developer Notes:
    `PetscOptionsPublish` is set in `PetscOptionsCheckInitial_Private()` with `-saws_options`. When `PetscOptionsPublish` is set the
    loop between `PetscOptionsBegin()` and `PetscOptionsEnd()` is run THREE times with `PetscOptionsPublishCount` of values -1,0,1.
     Otherwise the loop is run ONCE with a `PetscOptionsPublishCount` of 1.
+      \-1 - `PetscOptionsInt()` etc. just call `PetscOptionsGetInt()` etc.
.      0   - The GUI objects are created in `PetscOptionsInt()` etc. and displayed in `PetscOptionsEnd()` and the options
              database updated with user changes; `PetscOptionsGetInt()` etc. are also called.
-      1   - `PetscOptionsInt()` etc. again call `PetscOptionsGetInt()` etc. (possibly getting new values), in addition the help message and
              default values are printed if -help was given.
     When `PetscOptionsObject.changedmethod` is set this causes `PetscOptionsPublishCount` to be reset to -2 (so in the next loop iteration it is -1)
     and the whole process is repeated. This is to handle when, for example, the `KSPType` is changed thus changing the list of
     options available so they need to be redisplayed so the user can change the. Changing `PetscOptionsObjects.changedmethod` is never
     currently set.

  you should ALWAYS initialize `value` if you access it without first checking that the `set` flag is `PETSC_TRUE`.

  The `currentvalue` passed into this routine does not get transferred to the output `value` variable automatically.

  See `PetscOptionsEList()` for when the choices are given in a string array

  To get a listing of all currently specified options,
  see `PetscOptionsView()` or `PetscOptionsGetAll()`

  PetscOptionsDeprecated - mark an option as deprecated, optionally replacing it with `newname`

  Logically Collective

  Input Parameters:

. newname - the new option, or `NULL` if option is purely removed
. version - a string describing the version of first deprecation, e.g. "3.9"
- info    - additional information string, or `NULL`.

  Notes:
  If `newname` is provided then the options database will automatically check the database for `oldname`.

  The old call `PetscOptionsXXX`(`oldname`) should be removed from the source code when both (1) the call to `PetscOptionsDeprecated()` occurs before the
  new call to `PetscOptionsXXX`(`newname`) and (2) the argument handling of the new call to `PetscOptionsXXX`(`newname`) is identical to the previous call.

  If newname is provided, the old option is replaced. Otherwise, it remains in the options database.
