> HnswGraphBuilder has a few tunables: maxConnections, beamWidth, and we may 
> add a few more, such as whether to use a diversity heuristic when choosing 
> neighbors to link in the graph. Currently these are locked to defaults set by 
> global variables. Instead we should provide some interface for configuring 
> them. The best candidate so far seems to be to add them either as attributes 
> on a FieldType, or as Codec level configurations.
