Comment (by hinder):

 (Erik and I already discussed this out of TRAC - I put the following here
 for the benefit of others)

 This makes for a much more complicated !McLachlan_BSSN.m.  I would rather
 that the splitting itself was done within Kranc.  You could give Kranc the
 original unsplit calculations, and give it patterns to match against the
 terms which are candidates for splitting.  Kranc would then process the
 calculations and generate the different variants. This way, the splitting,
 which is an implementation/optimisation detail, is hidden from the end-
 user, who only has to worry about the equations.  It's good to have this
 patch here in TRAC so that we can use it as a reference, now that I see
 the idea of what you are trying to do.  We just need to move the logic
 from this patch into Kranc.
