implement handling and/or expressions

[esc]

As title. Fixes #148

[sklam]

1. Implementation is not handling more than one and/or. For example, x and y and z or x or y or z.

I used test like: (x > 0 and x < 10 and x) or (y > 0 and y < 10 and y)

2. if x and y is not handled. Need to add testing that uses and/or with branches and loops.

Yeah, it's still in progress. I'll let you know when it is ready for review.

I've converted this back to a draft as it was not yet ready for review.

I added code and tests to satisfy the above, not sure how complex to make the tests.
