The `ReplicatingInputFormat` can wrap any kind of `InputFormat` (with or
without RuntimeContext).
Therefore, it needs to extend `RichInputFormat` but overwrite the
`setRuntimeContext()` method and forward the context to its wrapped IF, if this
is also a `RichInputFormat`.
Please check the updated JavaDocs as well. The wrapped IF does not need to
be rich.

> User function that extend a RichFunction can access a {{RuntimeContext}}
> which gives the parallel id of the task and access to Accumulators and
> BroadcastVariables.
> Right now, Input and OutputFormats cannot access their {{RuntimeContext}}.
