title: Calculate point between two coordinates based on a percentage
body: <p>I am looking for a function that returns a point (lat, long) between two points (where I also specify their lat, long) and that point is based on a distance percentage.</p>
  
  <p>So, I specify Lat1, Lon1, Lat2, Lon2 and a % on the function and, it returns a point, for example, 20% distant from the first point to the second.</p>
