Detailed Description

Register subclasses of Question to create instances of them based on their type string.

This is a service interface. Obtain a pointer to its single instance via GetInstance().

Each Question subclass must be registered by calling Register(), which is typically done in the module activator class. After Question subclasses are registered, instances of them can be created with Create() based on their type string. This mechanism is primarily used for the deserialization of questions.
