Rugged::Walker.walk

Create a Walker object, initialize it with the given options
and perform a walk on the repository; the lifetime of the
walker is bound to the call and it is immediately cleaned
up after the walk is over.

The following options are available:

- +sort+: Sorting mode for the walk (or an OR combination
of several sorting modes).

- +show+: Tips of the repository that will be walked;
this is necessary for the walk to yield any results.
A tip can be a 40-char object ID, an existing +Rugged::Commit+
object, a reference, or an +Array+ of several of these
(if you'd like to walk several tips in parallel).

- +hide+: Same as +show+, but hides the given tips instead
so they don't appear on the walk.

- +oid_only+: if +true+, the walker will yield 40-char OIDs
for each commit, instead of real +Rugged::Commit+ objects.
Defaults to +false+.

- +simplify+: if +true+, the walk will be simplified
to the first parent of each commit.

Example:

  Rugged::Walker.walk(repo,
show: "92b22bbcb37caf4f6f53d30292169e84f5e4283b",
sort: Rugged::SORT_DATE|Rugged::SORT_TOPO,
oid_only: true) do |commit_oid|
	puts commit_oid
end

generates:

  92b22bbcb37caf4f6f53d30292169e84f5e4283b
