Examples of com.google.collide.client.util.PathUtil

com.google.collide.client.util.PathUtil
Utility class for dealing with File paths on the client.
This class is immutable. TODO: We may need the equivalent of this on the server as well. If we do, might want to drop the use of native collections and put it in shared.
