Detect local arguments and functions used in a function

[samwaseda]

Following the effort in #155, I started trying to parse variables as well. Edits will follow....

@liamhuber I started looking into the possibility of including variables as well. Frankly I'm also not really convinced but I still would like to explore the possibility

I just had a discussion with @XzzX and we think we can keep the current implementation is maybe not quite as useless as I had imagined, because with this implementation it is now possible to throw an error as soon as an external variable is used.

because with this implementation it is now possible to throw an error as soon as an external variable is used.

Failing cleanly is infinitely better than looking like everything is well-provenanced when it isn't. However, I still think that restricting "ok locally defined stuff" to mean "don't use any symbols outside your function definition" is going to turn out to be a more annoying, more restrictive, more-work solution than telling people "you'll have to use well-versioned code to contribute to the KG". As an intermediate step towards catching and leveraging these external symbols, this still seems like solid progress though.
