Use Requires.jl to make LightGraphs a soft dependency?

It would mean that logging graphs would only be enabled in you had LightGraphs loaded.

But then we can cut down our dependencies significantly.

I'm personally in favor of anything that cuts down on the dependencies of this package.
But, didn't you have reservations against using Requires.jl ? Or those issues have been fixed?

[oxinabox]

I do have reservations about Requires.jl,
it causes a big increase in load time when you load the package that is hidden behind it gets loaded.

but I think that is worth it to drop the dependency.

It also voids your ability to check versions of the Required package, but that is not so bad since we only use fairly basic functions that are unlikely to change
