Fact Set Implementation

The implementation requires high performance for the FactSet.getAspectValues(Fact) method and the FactSet.getFacts(AspectValue) method. It should be noted that a fact will map to multiple aspect values and that an aspect value will, in general, map to multiple facts.

To support this performance requirement, a FactSet is implemented using three one-to-many maps . These are based on synchronised versions of the Google Collections Multimap.
