// This is the main entry point for all resource lookup.
// Research shows that by far the most common scenario is to pass in a bundle object, a resource name, and a resource type, using the default localization.
// It is probably the case that more than a few resources will be looked up, making the cost of a readdir less than repeated stats. But it is a relative waste of memory to create strings for every file name in the bundle, especially since those are not what are returned to the caller (URLs are). So, an idea: cache the existence of the most common file names (Info.plist, en.lproj, etc) instead of creating entries for them. If other resources are requested, then go ahead and do the readdir and cache the rest of the file names.
// Another idea: if you want caching, you should create a bundle object. Otherwise we'll happily readdir each time.
