Reasons for converting to json

1. XML DOM objects are heavy objects, we should convert the XML to light weight object (json, map) as early in the dag as possible i.e. as soon as we receive the xml. 
2. We do not need to validate XML, we are treating them like json objects. So we do not need them to conform to any XSD schema or DTD.
3. We do not need to reuse the XML. We need a way of quickly getting the data out of the xml and send to down stream operators. The most agreed upon such objects are Maps and JSONObjects.

If you think the name of the operator is misleading, please suggest another name for what we are trying to achieve here.
