Coding Challenge #58: 3D Earthquake Data Visualization

In this Coding Challenge, I follow up on the Earthquake Data Visualization challenge (https://youtu.be/ZiYdOwOrGyc) and create a 3D version in Processing(Java) using spherical coordinates. I also discuss some 3D vector math including the cross product.
