Constants

const MaxRelationships = 10

MaxRelationships is the maximum number of types of relationships tracked. Out-of-the-box, Tomolink supports tracking of up to 10 different kinds of relationships. This can be changed and Tomolink recompiled, but note that raising this value indiscriminantly may have an impact on startup times!
