… guess so that the following conditions are all met:

1. Hessian is indefinite
2. Directional Derivative is negative
3. The initial guess is between a local maximum and a global minimum

This causes Newton's method with and without line search to converge to the local maximum

…te by reversing negative eigenvalues. Added optional enum parameter to NewtonMinimizer class to allow for future implementations of other methods of Hessian modification.
