//Bug#4251902 Make Proxy Indirection writable and readable to deployment xml.  useProxyIndirection() now creates
//a ProxyIndirectionPolicy that includes not only the interfaces of the referenceClass, but also all the super
//interfaces of the referenceClass.  To test this new functionality, Computer, ComputerImpl, DesktopComputer and
//DesktopComputerImpl have been added.
