pyrules | first go at implementing a generic Rule Engine | Rule Engine library

After a few hours of work, I figured out a way to get ast.literal_eval() to work! My logic is to look at the two sides of, say, x>2, i.e. x and 2, make sure these are safe by evaluating both with literal_eval, and then run it through my check() function, which does the evaluation. Same for z in ('def', 'abc'): First make sure both z and ('def', 'abc') are safe, then do the actual boolean checking with the check() function.

Since I fully trusted my inputs I could've done the easier eval() way, but just wanted to be double-cautious. And wanted to build some code for everybody out there who have security issues (user inputs etc.) and need to safely evaluate logicals. Hope it helps somebody!

Please see my full code below, any comments/recommendations are welcome.
