MetaGraph does not accept SimpleGraph properly #31

Closed racinmat closed 2 years ago

racinmat commented 2 years ago 
using LightGraphs, MetaGraphs
g = LightGraphs.SimpleGraphs.grid([5, 24])
MetaGraph(g)

crashes with

that's because without parameters it does not dispatch to https://github.com/JuliaGraphs/MetaGraphs.jl/blob/master/src/metagraph.jl#L36.

Sorry, I missed the fact that it migrated to Graphs from LightGraphs.
