class LimitedSharingClassLoader extends URLClassLoader

A ClassLoader that delegates only certain classes to the parent, based on a regular expression. This is useful for creating an isolated class loader which shares some necessary classes (i.e. java and scala libraries) with the root class loader, so that instances of those classes can be freely used by isolated classes.

Resource loading behavior is not changed from a standard class loader (TODO?)
