module for exporting shared globs

 Sub::Exporter::GlobExporter is a Perl module that enables packages to share
 glob references with other modules. This allows your module to be subclassed,
 for the subclass to re-use the same glob when exporting, or to export a new
 one. This scheme provides extensibility by returning a collection validator,
 allowing arbitrary options to be passed to the globref locator.
