Adding JGroups support to JSDT

Today I checked back the changes to add a new JGroups reliable multicast support implementation for the Shared Data Toolkit for Java(TM) Technology

It was ridiculously easy. JSDT is so designed that each new multicast implementation needs to implement the com.sun.media.jsdt.multicast.Multicast interface which defines five methods. Here's what the new code looks like.

Since 1997, JSDT has has the ability to dynamically load the transport protocol (a special Java class) to use. I even have a patent for it.

Because of this approach, combined with great JGroups API documentation and demo examples and the willingness of the JGroups author Bela Ban to help answer a couple questions I had, this was a trivial job.
