- Implemented OperatorNode.isUnary and OperatorNode.isBinary.
...
- Explicit checks for number of arguments everywhere working with `OperatorNode` and `FunctionNode`.
- Fixed #1014 : derivative silently ignoring additional arguments.

Shortened up some of the more verbose test cases for which simplifications are possible. Used config.number on ConstantNodes that I missed on my original commits.

Added a test case for nthRoot where the root is variable. Now handles a variable base log, and added a test case. Adjusted the chain rule to be after the switch statement (saves ~1640 bytes and is more modular).

Complete structure of derivitive function. Most operators are complete, with a few functions as well. Still does not handle argument errors well, even though it returns the same it received.
