/**
 * This will find the distance between a point and a plane
 * 1. I will first take in the point and the equation of the plane 
 *2. I will then find a point on a plane and the vector between that point and the point above the plane  
 * 3.find the magnitude of the projection of the vector we find in 2 unto the vectos from the plane equation
