Expose DOT-specific keywords

[0xmichalis]

A user shouldn't manually construct DOT keywords before adding them in the attributes of a graph object. All the names mentioned in here should be exposed by this package.

I agree, it would be safer to have all the attributes so stringly typed.

We could make type safe and constrained methods to build the map[string]string and not break the current API.

This is quite a long list of things to implement and, unfortunately, I am currently very busy, but I would be open to contribution.
I am very sorry and I hope that this is an acceptable answer?

Thanks for the answer! No worries, it's good that you agree about the issue. I might submit a PR if time permits it.:)

I look forward to it :)

I have decided that we are going to make a breaking change to return some errors.
Or at least that is what this proposal is about
#23
Hopefully we can then fix this keyword problem as well.

Merged pull request #25 with some attribute validation.
