This commit adds a few functions that implement various versions
of the SNS-IK solver algorithms, along with a set of unit tests.
This code is primarily used for reference and debugging, rather
than as a well-packaged product.
Following up on the naming question: I propose that we keep the names as they are for now, but then come up with a better (and standardized) naming convention once we get a larger set of methods working.
