Normalizes the arguments and passes it on to find_templates.

Handles templates caching. If a key is given and caching is on always check the cache before hitting the resolver. Otherwise, it always hits the resolver but if the key is present, check if the resolver is fresher before returning it.
# File lib/action_view/template/resolver.rb, line 181 def cached(key, path_info, details, locals) name, prefix, partial = path_info if key @cache.cache(key, name, prefix, partial, locals) do yield end else yield end end

This is what child classes implement. No defaults are needed because Resolver
guarantees that the arguments are present and normalized.
