/** @class AnalysisDataService AnalysisDataService.h Kernel/AnalysisDataService.h

    The Analysis data service stores instances of the Workspace objects and 
    anything that derives from emplate class DynamicFactory<Mantid::Kernel::IAlgorithm>them.  This is the primary data service that
    the users will interact with either through writing scripts or directly
    through the API. It is implemented as a singleton class.

    This is the manager/owner of Workspace* when registered.
