##### Create a hierarchical random graph from an igraph graph

hrg creates a HRG from an igraph graph. The igraph graph must be a directed binary tree, with $n-1$ internal and $n$ leaf vertices. The prob argument contains the HRG probability labels for each vertex; these are ignored for leaf vertices.

hrg(graph, prob)
##### Arguments
graph

The igraph graph to create the HRG from.

prob

A vector of probabilities, one for each vertex, in the order of vertex ids.

##### Value

hrg returns an igraphHRG object.
