1.0.0

This is not a backwards compatible release.

Additions:

Added SampleByKey, which provides a way to sample tuples based on certain fields.
Added Coalesce, which returns the first non-null value from a list of arguments like SQL's COALESCE.
Added BagGroup, which performs an in-memory group operation on a bag.
Added ReservoirSample
Added In filter func, which behaves like SQL's IN
Added EmptyBagToNullFields, which enables multi-relation left joins using COGROUP
Sessionize now supports long values for timestamp, in addition to string representation of time.
BagConcat can now operate on a bag of bags, in addition to a tuple of bags
Created TransposeTupleToBag, which creates a bag of key-value pairs from a tuple
SessionCount now implements Accumulator interface
DistinctBy now implements Accumulator interface
Using PigUnit from Maven for testing, instead of checked-in JAR
Added many more test cases to improve coverage
Improved documentation

Changes:

Moved WeightedSample to datafu.pig.sampling
Using Pig 0.11.1 for testing.
Renamed package datafu.pig.numbers to datafu.pig.random
Renamed package datafu.pig.bag.sets to datafu.pig.sets
Renamed TimeCount to SessionCount, moved to datafu.pig.sessions
ASSERT renamed to Assert
MD5Base64 merged into MD5 implementation, constructor arg picks which method, default being hex

Fixes:

Quantile now outputs schemas consistent with StreamingQuantile
Necessary fastutil classes now packaged in datafu JAR, so fastutil JAR not needed as dependency
Non-deterministic UDFs now marked as so

0.0.10

Additions:

CountEach now implements Accumulator
Added AliasableEvalFunc, a base class to enable UDFs to access fields in tuple by name instead of position
