We will provide a generic interface that will allow you to create solver 
requests like:

        doUpdate( "foo" ); // one Solvable

        for_each( c.begin(), c.end(), DoUpdate() ); // a collection 

Schubi and I am about to get this going. This will replace the old 
solver.solver.addRequires etc. interface.
