Version 0.2 of InMin library

I am happy to announce version 0.2 of the InMin library (see).

The new feature in this release is constrained Levenberg-Marquardt, where the parameters are constrained to lie in a box. To use this feature simply specify the constraint in the box parameter.

Under the hood, this release also has the code for active set constrained quadratic optimisation (however this feature is not yet exposed at the C-level API).

Hope you find these new features useful!
