Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Reynold Xin

1. Removed UDFRegistration as a mixin in SQLContext and made it a field
("udf"). This removes 45 methods from SQLContext.
2. For Java UDFs, renamed dataType to returnType.
3. For Scala UDFs, added type tags.
4. Added all Java UDF registration methods to Scala's UDFRegistration.
5. Better documentation
