Dmitriy V. Ryaboy updated PIG-1563:
-----------------------------------
Attachment: PIG_1563.patch
Updated the functions with the appropriate argToFunc mappings, added tests.
Also tried on current build of trunk to make sure all the up- and down- casting
magic works, and it does.
Note the new methods in test.Utils and pig.impl.util.Utils -- pretty handy.
