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