129 
130   Developer Notes:
131     PetscOptionsPublish is set in PetscOptionsCheckInitial_Private() with -saws_options. When PetscOptionsPublish is set the
132 $             loop between PetscOptionsBegin() and PetscOptionsEnd() is run THREE times with PetscOptionsPublishCount of values -1,0,1 otherwise
133 $             the loop is run ONCE with a PetscOptionsPublishCount of 1.
134 $             = -1 : The PetscOptionsInt() etc just call the PetscOptionsGetInt() etc
135 $             = 0  : The GUI objects are created in PetscOptionsInt() etc and displayed in PetscOptionsEnd() and the options
136 $                    database updated updated with user changes; PetscOptionsGetInt() etc are also called
137 $             = 1 : The PetscOptionsInt() etc again call the PetscOptionsGetInt() etc (possibly getting new values), in addition the help message and
138 $                   default values are printed if -help was given.
139 $           When PetscOptionsObject.changedmethod is set this causes PetscOptionsPublishCount to be reset to -2 (so in the next loop iteration it is -1)
140 $           and the whole process is repeated. This is to handle when, for example, the KSPType is changed thus changing the list of
141 $           options available so they need to be redisplayed so the user can change the. Chaning PetscOptionsObjects.changedmethod is never
142 $           currently set.
