> As a result of defining a virtual resource tree (SLING-197) we have a need to 
> modify the ResourceResolver API in two respects:
> (1) Add ResourceResolver.resolve(String absPath)
> This method behaves exactly as ResourceResolver.resolve(HttpServletRequest) 
> except, that the latter method may make use of additional request properties, 
> such as request headers or parameters while the resolve(String) method only 
> has the string to work on.
> Currently the resolve(HttpServletRequest) method does nothing more than use 
> the HttpServletRequest.getPathInfo() to resolve the resource, thus both 
> implementations would actually be equivalent.
> The absPath argument is an absolute path. Resolution fails for relative paths.
> (2) Support relative paths in ResourceResolver.getResource(String path)
> Currently this method is defined to throw a SlingException if the path is 
> relative. This should be changed such that the ResourceResolver applies some 
> search path logic to find a resource with the given relative path
> The search path logic is comparable to how *nix systems use the PATH 
> environment variable.
> This method may then be used by multiple users such as Servlet/Script 
> resolution.
> (3) Add ResourceResolver.map(String) method
> This method applies the reverse mappings of the 
> ResourceResolver.resolve(String absPath) method to return a path suitable for 
> both resolver() methods. This allows for the creation of link paths for 
> resources.
