61     PetscOptionsBegin - Begins a set of queries on the options database that are related and should be
62      displayed on the same window of a GUI that allows the user to set the options interactively. Often one should
63      use PetscObjectOptionsBegin() rather than this call.

65    Synopsis:
66     #include <petscoptions.h>
67     PetscErrorCode PetscOptionsBegin(MPI_Comm comm,const char prefix[],const char title[],const char mansec[])
68 
69     Collective on MPI_Comm
70 
71   Input Parameters:
72 +   comm - communicator that shares GUI
73 .   prefix - options prefix for all options displayed on window
74 .   title - short descriptive text, for example "Krylov Solver Options"
75 -   mansec - section of manual pages for options, for example KSP
76 
77   Level: intermediate
78 
79   Notes: Needs to be ended by a call the PetscOptionsEnd()
80          Can add subheadings with PetscOptionsHead()
81 
82   Developer notes: PetscOptionsPublish is set in PetscOptionsCheckInitial_Private() with -saws_options. When PetscOptionsPublish is set the
83 $             loop between PetscOptionsBegin() and PetscOptionsEnd() is run THREE times with PetscOptionsPublishCount of values -1,0,1 otherwise
84 $             the loop is run ONCE with a PetscOptionsPublishCount of 1.
85 $             = -1 : The PetscOptionsInt() etc just call the PetscOptionsGetInt() etc
86 $             = 0  : The GUI objects are created in PetscOptionsInt() etc and displayed in PetscOptionsEnd() and the options
87 $                    database updated updated with user changes; PetscOptionsGetInt() etc are also called
88 $             = 1 : The PetscOptionsInt() etc again call the PetscOptionsGetInt() etc (possibly getting new values), in addition the help message and
89 $                   default values are printed if -help was given.
90 $           When PetscOptionsObject.changedmethod is set this causes PetscOptionsPublishCount to be reset to -2 (so in the next loop iteration it is -1)
91 $           and the whole process is repeated. This is to handle when, for example, the KSPType is changed thus changing the list of
92 $           options available so they need to be redisplayed so the user can change the. Chaning PetscOptionsObjects.changedmethod is never
93 $           currently set.
