Heads-up: LightGraphs and Julia 0.6

[sbromberger]

Hi all,

LightGraphs is preparing for a fairly large upgrade with Julia 0.6, and I wanted to make you aware of what we're doing. Very few things are breaking, but there will be some potential performance improvements that you might be able to take advantage of.

In a nutshell: we're abstracting Graph and DiGraph, renaming them to SimpleGraph and SimpleDiGraph*, and parameterizing vertex indices to <: Integer. This will allow you to create, e.g., SimpleGraph{UInt8}s that will be much more space-efficient if you have graphs that are < 256 vertices.

*While we plan on more abstractions (e.g., for weighted graphs) in the future, for now Graph and DiGraph will continue to work and will continue to default to SimpleGraph, and the default parameterization for both Simple(Di)Graphs and (Di)Graphs will be Int.

Feel free to review the (very long) WIP at sbromberger/LightGraphs.jl#541 - your feedback would be greatly appreciated.

No action necessary as far as I can tell.
