Don Cross dd02364fb4 C global solar eclipse: calculate longitude of the peak eclipse.
Use sidereal time to calculate the longitude of the point
on the Earth's surface where the Moon's shadow ray strikes it.
In the unit test, ignore glancing blows, but if the shadow
ray passes within 6100 km of the Earth's center, verify that
the total angular error is within about a quarter degree.
