Comment (by barry.wardell):

 It modifies McLachlan_BSSN and the changes are included in the ML_BSSN
 thorn. The changes involve the addition of some extra terms which are only
 computed if the CCZ4 system is chosen by setting the "formulation"
 parameter to 1. This defaults to 0, corresponding to the existing BSSN
 system. There is also the addition of a single grid scalar for the CCZ4
 Theta variable. Attached is a diff of McLachlan_BSSN.m between master and
 CCZ4 branches.
