\section{Purpose}
\label{sec:aux}
This thorn is completely trivial (there's already more words in the
documentation than in the code). The point is to allow clean coupling
of matter thorns and spacetime evolution thorns. By making a spacetime
thorn (such as BSSN) a friend of ADMCoupling it can know about the
variables of the matter thorns (such as Whisky) as long as they are
also friends of ADMCoupling, and then the appropriate stress energy
tensor terms can be included through the {\tt CalcTmunu} interface.
This avoids explicit dependencies between the spacetime and matter
evolution thorns. Note that we need to do the same for certain
analysis thorns, such as ADMConstraints.
