Module documentation

Hyperbolic-Wavefront Task: produces the shape of the incoming wavefront, using pulse arrival times at each antenna. Stripped version of Wavefront Task; this version only calculates the best-fitting hyperbolic wavefront and az/el direction, given the eventID, arrival times, arrival time uncertainties, antenna positions, station names per antenna, and a shower core position (x and y) as input.
