    Use the system wide materializer with stream attributes or configuration settings to change defaults. Since 2.6.0.
    
    Scala API: Creates an ActorMaterializer that can materialize stream blueprints as running streams.
    The required ActorRefFactory (which can be either an ActorSystem or an ActorContext) will be used to create one actor that in turn creates actors for the transformation steps.
    The materializer's ActorMaterializerSettings will be obtained from the configuration of the context's underlying ActorSystem.
    The namePrefix is used as the first part of the names of the actors running the processing steps. The default namePrefix is "flow". The actor names are built up of namePrefix-flowNumber-flowStepNumber-stepName.
