Graph interfaces, bespoke graphs for every occasion

We presented the LightGraphs.jl package with James for anyone in need of a simple & extensible graph library in Julia, the core interface for abstract graphs and essential algorithms included.

Anyone can come up with their own graph type, and we show it by building the simplest graph type from an adjacency matrix, implementing the LightGraphs interface, and then re-using the whole ecosystem on this type for free.
