In 3D Euclidian space, find a collection of mass points lying on the line [0,1]
1) There is more than 1 point.
2) Each point has non-zero mass.
3) The total mass is 1.
4) Each point attracts each other point with inverse square gravitational
5) The entire system is in static equilibrium - that is, the total force on
each point exists and is zero.
