//    Jeremy Meredith, Thu Nov  2 14:07:34 PST 2000
//    Changed the file initialization.  Apparently substr() may not portably 
//    be a const method of strings....
//
//    Hank Childs, Tue Jun 12 20:01:55 PDT 2001
//    Incorporate data specifications and the load balancer.
//
//    Jeremy Meredith, Thu Jul 26 12:08:42 PDT 2001
//    Fixed a bug passing the data file name to the load balancer.
//
//    Hank Childs, Thu Jul 26 20:17:56 PDT 2001
//    Re-enable caching by checking data specifications.
//
//    Brad Whitlock, Mon Oct 22 18:33:37 PST 2001
//    Changed the exception keywords to macros.
//
//    Jeremy Meredith, Fri Nov  9 10:24:23 PST 2001
//    Replaced netPool with netMRU, and simply made it release its
//    data, not delete the whole network. Made is only set the data
//    specification, not the pipeline specification yet.
//
//    Hank Childs, Fri Dec 14 17:39:36 PST 2001
//    Add support for using a more compact version of sil attributes.
//
//    Sean Ahern, Mon May 13 17:24:25 PDT 2002
//    Refactored to start support for a tree-based network scheme.
//
//    Sean Ahern, Tue May 28 09:47:21 PDT 2002
//    Added tree-based networks.
//
//    Brad Whitlock, Fri Jun 28 14:03:49 PST 2002
//    I renamed Network to DataNetwork to make the Windows compiler happy.
//
//    Hank Childs, Thu Sep 12 11:11:16 PDT 2002
//    There was an issue with multiple networks sharing NetnodeDBs, so I
//    made them all have their own reference.
//
//    Jeremy Meredith, Thu Oct 24 16:03:39 PDT 2002
