we should be able to simply instantiate a named target and run "install"

    >>> from releasemanager.installer.target import NamedTarget
    >>> from releasemanager.tests.mock.resource import MockResource
    >>> nt = NamedTarget('test', 'named_target_template')
    >>> resource = MockResource('test').data
    >>> nt.install(resource, 'http://svn.fake.com/svn/project/trunk; 9999')
