/*

These objects represent both plain files and folders.  The workspace is used to find the necessary icons, titles, and file information.  Files are a subclass of IconFolder so that they can be organized in a full directed graph.

File objects are cached, so that every filename will have exactly one File object.  The caching not only improves efficiency, but also shows off how multiple viewers can easily reflect changes to the same file.
