Show progress in DaggerWebDash

Hi,

this is an excellent library. Looks like we can view the graph and view the graph stats as well.

Do we think its possible to see all of this in realtime? as in, in a view, show the whole graph and the currently executing node, along with pending nodes? For instance, the benchmark scripts, show the whole graph, highlighting the currently executing node and the pending nodes, along with stats. this is extremely useful for long-running processes.

thanks
Roh
