* @brief A class that makes it safe and easy to use DataEngines
*
* DataEngineConsumer provides access to DataEngines, which are internally reference
* counted and shared between all users of them. The only public method provided is
* dataEngine which returns engines upon request.
*
* When the DataEngineConsumer class is deleted, all engines accessed using it are
* de-referenced and possibly deleted (in the case that there are no other users of
* the engine in question).
*
* DataEngineConsumer can be subclassed by other C++ classes to allow this simple
* API to be used directly from these classes in a convenient manner.

* once this DataEngineConsumer instance is deleted.
*
* It is safe and fast to request the same engine more than once.
*
* @param name the name of the DataEngine. This corresponds to the plugin name
