Expandalyzer for ArchivesSpace and ExploreUK per UK_Digi_Arch

This extension automatically expands or collapses all nested records in ArchivesSpace and ExploreUK. For very large pages, it may require multiple clicks to un-nest folders. For absolutely huge pages, it may cause the browser tab to hang up. Otherwise, it does the trick and allows you to search effectively within large nested pages.
