Allow setting globals for access by the scoring rules
-----------------------------------------------------

                 Key: JBRULES-2700
                 URL: https://jira.jboss.org/browse/JBRULES-2700
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: drools-planner
            Reporter: Wouter Horré
            Assignee: Mark Proctor

Currently, it is not possible to set a global variable in the working memory used by the solver. If a scoring rule needs an external helper for calculating scores (e.g. a dependency injected with OSGi DS), a workaround using a static variable in some class accessible by the scoring rules is needed.

The easiest implementation is probably a new method in the Solver interface:
public WorkingMemory getWorkingMemory();
which provides access to the working memory used by the solver.
