Examples:

    my $r = Pithub::GitData::References->new;
    my $result = $r->create(
        user => 'plu',
        repo => 'Pithub',
        data => {
            ref => 'refs/heads/master',
            sha => '827efc6d56897b048c772eb4087f854f46256132' .

Get a Reference

    GET /repos/:user/:repo/git/refs/:ref

Parameters:

=over

=item *

B<user>: mandatory string

=item *

B<repo>: mandatory string

=item *

B<ref>: mandatory string

=head2 list

=over

=item *

Get all References

    GET /repos/:user/:repo/git/refs

This will return an array of all the references on the system,
including things like notes and stashes if they exist on the server.
Anything in the namespace, not just heads and tags, though that
would be the most common.

Parameters:

=over

=item *

B<user>: mandatory string

=item *

B<repo>: mandatory string

=back

Examples:

    my $r = Pithub::GitData::References->new;
    my $result = $r->list(
        user => 'plu',
        repo => 'Pithub',
    );

=item *

You can also request a sub-namespace. For example, to get all the
tag references, you can call:

    GET /repos/:user/:repo/git/refs/tags

Parameters:

=over

=item *

B<user>: mandatory string

=item *

B<repo>: mandatory string
