>
> In some cases, the properties we want in the VertexEdges implementation
> during input may differ from the ones we want during computation.
> Two examples:
> 1) During input, we want to keep only the top K edges according to weight, so
> we use a fixed-size min-heap. During computation, our algorithm needs fast
> random access, so we use a hash-map.
> 2) We have a VertexEdges implementation that's optimized for space and/or
> iteration speed, but has slow insertion. We can then use a different data
> structure that has fast insertion during input.
> We can add an option to specify a different VertexEdges class to be used in
> EdgeStore during input.
