> MapReduce C++ support
> Requirements
> 1. Allow users to write Map, Reduce, RecordReader, and RecordWriter functions in C++, rest of the infrastructure already present in Java should be reused.
> 2. Avoid users having to write both Java and C++ for this to work.
> 3. Avoid users having to work with JNI methods directly by wrapping them in helper functions.
> 4. The interface should be SWIG'able.
