Provide new Parser constructor

What I need is an option like

parseYangModels(File yangFile, File directory)

Currently I need to do something like this this :

List<File> yangFiles = new ArrayList<File>();
yangFiles.add(new File("IF-MIB.yang"));
yangFiles.add(new File("iana-if-type.yang"));
yangFiles.add(new File("SNMPv2-TC.yang"));
yangFiles.add(new File("ietf-yang-types.yang"));

YangModelParser parser = new YangParserImpl();
Set<Module> modules = new HashSet<Module>();
modules = parser.parseYangModels(yangFiles);

Of course hard-coding won't work, so otherwise I'll need to parse each Yang file and compute the import transitive closure myself.

I think this would be a useful addition to the API.
