The use of `type-of` to choose how to process graphs will make extension impossible, because newly-introduced subtypes of `graph` and `digraph` wouldn't satisfy the right guards. Replaced such uses of `type-of` with a combination of newly-introduced generic functions and `typep`.
Bumped the version from 0.0.0 to 0.1.0 so that `:version` can be used to detect the extensible version of the graph library. Also added my name to the list of authors.

The use of
type-ofto choose how to process graphs will make extension impossible, because newly-introduced subtypes ofgraphanddigraphwouldn't satisfy the right guards.Replaced such uses of
type-ofwith a combination of newly-introduced generic functions andtypep.I was considering extending the existing classes using a mixin that would handle attaching attributes to nodes and edges, but realized that would break methods that used
type-ofto distinguish between digraphs and graphs. This PR would clear the way to making that change.
