69    Synopsis: PetscErrorCode PetscOptionsBegin(MPI_Comm comm,const char prefix[],const char title[],const char mansec[])
70 
71     Collective on MPI_Comm
72 
73   Input Parameters:
74 +   comm - communicator that shares GUI
75 .   prefix - options prefix for all options displayed on window
76 .   title - short descriptive text, for example "Krylov Solver Options"
77 -   mansec - section of manual pages for options, for example KSP
78 
79   Level: intermediate
80 
81   Notes: Needs to be ended by a call the PetscOptionsEnd()
82          Can add subheadings with PetscOptionsHead()
83 
84   Developer notes: PetscOptionsPublish is set in PetscOptionsCheckInitial_Private() with -options_gui. When PetscOptionsPublish is set the
85 $             loop between PetscOptionsBegin() and PetscOptionsEnd() is run THREE times with PetscOptionsPublishCount of values -1,0,1 otherwise
86 $             the loop is run ONCE with a PetscOptionsPublishCount of 1.
87 $             = -1 : The PetscOptionsInt() etc just call the PetscOptionsGetInt() etc
88 $             = 0  : The GUI objects are created in PetscOptionsInt() etc and displayed in PetscOptionsEnd() and the options
89 $                    database updated updated with user changes; PetscOptionsGetInt() etc are also called
90 $             = 1 : The PetscOptionsInt() etc again call the PetscOptionsGetInt() etc (possibly getting new values), in addition the help message and
91 $                   default values are printed if -help was given.
92 $           When PetscOptionsObject.changedmethod is set this causes PetscOptionsPublishCount to be reset to -2 (so in the next loop iteration it is -1)
93 $           and the whole process is repeated. This is to handle when, for example, the KSPType is changed thus changing the list of
94 $           options available so they need to be redisplayed so the user can change the. Chaning PetscOptionsObjects.changedmethod is never
95 $           currently set.
