+e.g., a *-1-category (that is, a 1-category with an involution of the morphisms
+reversing source and target) or a pivotal 2-category,
+(\cite{MR1686423, 0908.3347,1009.0186}),
 we can construct a system of fields as follows.
 Roughly speaking, $\cC(X)$ will the set of all embedded cell complexes in $X$
 with codimension $i$ cells labeled by $i$-morphisms of $C$.
