    136:   Developer Notes:
    137:       PetscOptionsPublish is set in PetscOptionsCheckInitial_Private() with -saws_options. When PetscOptionsPublish is set the
    138:       loop between PetscOptionsBegin() and PetscOptionsEnd() is run THREE times with PetscOptionsPublishCount of values -1,0,1.
    139:       Otherwise the loop is run ONCE with a PetscOptionsPublishCount of 1.
    140: +      \-1 - PetscOptionsInt() etc. just call PetscOptionsGetInt() etc.
    141: .      0  - The GUI objects are created in PetscOptionsInt() etc. and displayed in PetscOptionsEnd() and the options
    142:                database updated with user changes; PetscOptionsGetInt() etc. are also called.
    143: -      1 - PetscOptionsInt() etc. again call PetscOptionsGetInt() etc. (possibly getting new values), in addition the help message and
    144:               default values are printed if -help was given.
    145:       When PetscOptionsObject.changedmethod is set this causes PetscOptionsPublishCount to be reset to -2 (so in the next loop iteration it is -1)
    146:       and the whole process is repeated. This is to handle when, for example, the KSPType is changed thus changing the list of
    147:       options available so they need to be redisplayed so the user can change the. Changing PetscOptionsObjects.changedmethod is never
    148:       currently set.
