object PathIdentifierStore (source)
Singleton class which stores the mapping from a list of edges to IDs.
Let's say we have 3 edges along a path with edge IDs 6, 3 and 33.
We serialize these edge IDs into the String "6,3,33".
This serialized String will be the key in our pathEdgeSerializationStore HashMap. And it will be the value
in our pathIdentifierStore HashMap. We map this String to a generated ID.
