Detailed Description

The Analysis data service stores instances of the Workspace objects and anything that derives from template class DynamicFactory<Mantid::Kernel::IAlgorithm>.

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.
