Experimental Excel ORM library

Limitations

• Every sheet maps to only ONE POJO.
• Sadly, every time you need to update any data, whole sheet of the excel will be rewritten. This will be a major problem if data is huge.
• Only String, Integer, Double, BigInteger, Long, Boolean and Date classes are supported.
