Computes the surface of the parabolic mirror of the requested aperture and f number. Finds the closest sphere. Shows spherical aberration from the center of the sphere needed. Simulates Ronchi, Foucault and wire tests, and produces animations. See design_mirror_simulate_ronchi_foucault_wire.ipynb

Analysis of wire test in terms of surface accuracy.

To create simulations and animations of the Ronchi/Foucault/wire tests, requires pathos for multiprocessing (https://pypi.org/project/pathos/):

pip install pathos
