    @mxm , I've ported all existing IO formats to Rich IO formats. The unit test is consistently passing now.
    
    I also added a `postConfigure` function which allows user to access runtime context and setup things which use the runtime context, for example, accumulators. Its usage can be found in the unit test I've added. I found it impossible to guarantee the existence of `RuntimeContext` in the `configure` function itself.

> 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}}.
