Lookup GSPs by Layout

In Grails' implementation of Sitemesh, GSP pages can have a <meta name=layout/> tag, where the value corresponds to a layout GSP page (such as the default 'main.gsp') under grails-app/view/layouts/. On a large project with both internal and external sides, it is possible to have a large number of layouts, each used by dozens of different pages. It would be extremely useful to be able to lookup all GSPs that are using a particular layout. So if I was viewing the "educational.gsp" layout, I could (for example) "CMD click" the meta name=layout tage, and be given a dropdown or context menu of all GSPs using this layout. Since the format for this tag is virtually standardized (there's little variation - the layouts are always where they belong), this shouldn't be a huge pain to track down - even if it just stuck with views that were "where they belong" under the views/ directory.

Start by tracing the plugin's existing GSP/Sitemesh support and how views under grails-app/view/layouts/ or the views/ directory are recognized. Determine where layout references can be discovered, then verify that selecting a layout such as educational.gsp presents the GSP pages using it through the requested dropdown or context menu.
