// Neat little shortcut for "reversing" the reference lists stored on other
// things - for example, tracks specify a "referenced tracks" property, and
// you would use this to compute a corresponding "referenced *by* tracks"
// property. Naturally, the passed ref list property is of the things in the
// wiki data provided, not the requesting Thing itself.
