version 0.2.0
-------------

Added deterministic functions (!fun) and a way to convert them to probabilistic
(!embed).
Changed the !index factor to accept only deterministic functions for indexing;
simple indexing var=val can be done using
!fun {cod: [{var: [val,..]}], dom: [], par: [0]}

Renamed the old !index factor to !sindex.

Added Multinom.random and Fun.random to generate random factors (for testing).
Added detect_noisy_or function for refactoring a probabilistic Multinom into a
noisy-OR.

Added a C generator and dump/evaluator functions.
Added tests.
Added command line scripts.
Added convenience functions index and reorder.
Make NumPy evaluator emit Multinoms.
Added documentation.
Removed yapgvb dependency from default installation.
