Class SubTreeIndexedTripleCollection

An indexed triple collection that uses our VDS.Common.Collections.MultiDictionary<TKey, TValue> and VDS.Common.Trees.BinaryTree`2 implementations under the hood for the index structures.

Remarks

A variation on TreeIndexedTripleCollection which structures the indexes slightly differently, this may give differing performance and reduced memory usage in some scenarios.
