This function finds the shortest path from each node to every other
reachable node in the graph. It is similar to [alg.dijkstra][], but
instead of returning a single-source array, it returns a mapping of
of `source -> alg.dijksta(g, source, weightFunc, incidentFunc)`.

This function takes an optional `weightFunc(e)` which returns the
weight of the edge `e`. If no weightFunc is supplied then each edge is
assumed to have a weight of 1. This function throws an Error if any of
the traversed edges have a negative edge weight.

This function takes an optional `incidentFunc(u)` which returns the ids of
all edges incident to the node `u` for the purposes of shortest path
traversal. By default this function uses the `outEdges` function on the
supplied graph.

This function takes `O(|V| * (|E| + |V|) * log |V|)` time.
