Description

A JsonLoader/JsonStorage implementation for Pig. This is based on Alan's implementation in the book (http://ofps.oreilly.com/titles/9781449302641/load_and_store_funcs.html). I made some minor changes:
1. Drop the jackson feature requires 1.01+. Since Hadoop 203+ bundles jackson 1.01, newer feature fails when running on Hadoop 203+.
2. Using Json format for schema. This borrows Dmitry's schema implememtation in PigStorage.
3. Some bug fixes.
