Rules Js Versions Save

Updated dependencies. No further changes.

Chaining rules with AND/OR

• Make closures work both sync or async. Closure invokers (Rule, RuleFlow, ClosureReducer) won't create a Promise and execute on the then if the called closure returned a sync result. Engine will always return promises, so high level API hasn't change.
• Totally remove co dependency
• Fix unit tests! There were a lot of false positives on tests due the removal of co-mocha from dependencies.

Reimplemented through native Promises

It was replaced by plain old co library.

This internal issue might cause huge delays on fact processing. By changing the clone algorithm from JSON.parse/stringify to Object.assign we achieved a 5x performance boost.

Added support for #6 and #7

Disabled required parameters validation at bind time (since it was broken)

Now closures implemented thorugh a class must define a do method instead of a process method (although, overwriting process is still an option`.

do method accepts non promise return values.

Major changes. Closure syntax consolidated. Reduced to minimum interfaces.
