Implement Newcomb solver for kink modeling #41

In recent issues I have implemented tearing mode solvers, but have never tested a standard Newcomb solver for testing ideal MHD instability. This issue documents the implementation and testing of such a model against the original results from Matsuoka:

Magnetohydrodynamic instabilities in a current- carrying stellarator - K. Matsuoka

The initial implementation has some problems. The main instability regions seem to be captured but do not match results from the paper. This requires further investigation.
