## Detailed Description

The ServiceManager class is in charge of the creation of concrete instances of Services.

The ApplicationMgr delegates the creation and bookkeeping of services to the ServiceManager. In order to be able to create services from which it is not know the concrete type it requires that the services has been declared in one of 3 possible ways: an abstract static creator function, a dynamic link library or an abstract factory reference.
