Remove nodeKind member from ExprTree, and replace it with a pure virtual method #3457
that all of the derived classes must implement. parent ticket #2541
Remove data members from classad Operation class, and create subclasses by arity #3457 parent ticket #2541
each subclass of Operation class will have only the necessary data members, so we don't waste space for
2nd & 3rd ExprTree pointers in nodes that have no need of them.

Make cluster name optional in BOSCO tools and submit files. #3593

Where there is just one cluster registered with BOSCO, the cluster name
no longer needs to be given on the command line of bosco_cluster
commands, and grid_resource doesn't need to be given in the submit file.
The submit file part is achieved using the SUBMIT_EXPRS config param.
bosco_cluster --test now tests all clusters if no name is given.
bosco_cluster --list now takes an optional argument that controls what
it prints for each cluster.
bosco_cluster now has an explicit limit of 254 clusters.
Add bosco_quickstart script, which  makes getted started easier.
Add htsub submit wrapper to Bosco.

It creates the Condor submit file for you.
