Implements a set of nshells Wolter Ellipsoid/Hyperboloid pairs using conics.h from ConicTracer. The component has two distinct modes of specifying the geometry: a) Via the radii vector, parametrized from largest to smallest radius with a length of 'nshells' b) By specifying radii rmax and rmin, between which a quadratic law distributes 'nshells' surfaces. The mirrors are assumed to be touching at the mid-optic plane, i.e. there is no gap between primary and secondary mirror. By definition the ratio between primary and secondary mirror glancing angles is 1/3. At present a single m-value is used for all mirrors.
