Changelog

0.4.0

Python3 support
Added support for == operator
Permit unicode in predicates
Support for case insensitive operators
Tested on python 2.7, 3.4, 3.5 & pypy
SHA: ccc76fb

0.3.6

Improve the optimization of LiteralSet by making sets as small as possible, and avoiding branches on low density sets.
SHA: e8dbdb4

0.3.5

Added Literal Set support. This allows for sane contains with a literal collection of Literal, Number, or Constant values.
SHA: 5a2d4f1

0.3.0

Fixed optimizer to handle missing cases
Internal change to use EvalContext instead of passing around multiple objects
.analyze() now return the EvalContext instead of a dict
Duplicate expressions are cached to avoid wasted re-evaluations. This allows expressions with low selectivity to still avoid being re-evaluated, even though they are not in a branch.
Export ast.Undefined from the pypred package, since it is generally useful for writing custom resolvers.
