Perfect velocity integration #39

Closed mattrdowney closed 6 years ago

mattrdowney commented 6 years ago

As per Wikipedia (https://en.wikipedia.org/wiki/Leapfrog_integration): "This is especially useful when computing orbital dynamics, as many other integration schemes, such as the (order-4) Runge-Kutta method, do not conserve energy and allow the system to drift substantially over time."

Additionally, integration will not utilize knowledge of the angle phi (which is primarily to allow the engine to work with every genre of game).

Missed this, but it was done as of issue #26: c724c2956d863d767f1b90c5b3438dd3ae1715ad
