Refactors somepath to print an adjacency list from "from" to "to", instead of
just the nodes. This allows other tools like modgraphviz to print the subgraph.
This is a breaking change. The previous behavior returned vertices; now it
returns edges. If you relied on the previous behavior, use:
my-application | digraph somepath <from> <to> | digraph nodes

For example, the following command:
cd $GOPATH/src/cloud.google.com/go && \
go mod graph | \
digraph allpaths cloud.google.com/go golang.org/x/text@v0.3.2 | \
modgraphviz | \
dot -Tpng -o graph.png
Generates the following graph.png: https://user-images.githubusercontent.com/3584893/60481727-df0a8680-9c4b-11e9-8df9-c581d599edd1.png
Also splits out the allpaths tests into their own test, and adds many test
cases.

- Move verbose usage docs to godoc, replace usage with terse description of
usage and commands.
- Add copyrights.
- Update usage to more canonical function format instead of const format.

Example: show the transitive closure of imports of the digraph tool itself:
% go list -f '{{.ImportPath}}{{.Imports}}' ... | tr '[]' ' ' |
digraph forward code.google.com/p/go.tools/cmd/digraph
+ basic test.
