> Currently, Vertex implements Writable, meaning that we depend on the user (except for
the default implementation) on the way the graph is serialised and deserialized. This means
we cannot do certain optimisations, and the user can actually add additional stuff to Vertex
more than Value, Id, Edges and halt state. By removing this possibility (or allowing them
to extend a default implementation) we take control of this.
