Comment (by Roland Haas):

There are no extra scheduled functions in the Cactus sense. I generate one helper function per thorn that is directly called by the flesh, mostly because this is the way grid variable registration is done as well (one function CactusBindingsVariables_${thorn}_Initialise per thorn to register its grid variables with the flesh) so having a CactusBindingsVarIndex_${thorn}_Initialise(void) seemed most natural.
