## Detailed Description

The IAlgManager is the interface implemented by the Algorithm Factory in the Application Manager to support management functions.

Clients use this interface to declare abstract algorithm factories, and to create concrete instances of algorithms. There are currently 3 methods for the declaration: static creator method (creator), an abstract factory (factory) or a sharable library (module).
