The function point-in-polygon that finds which plate belongs the point has been upgraded. Now, it uses the coordinates lon, lat and places the point and the polygon at the surface of a sphere using the boost library. It also calculates the distance from the point to the polygon using the functionalities of the boost library. Each point has a unique solution to the polygon that belongs to.
Also we generalised plates, such as, internally it does the conversion from xyz to lon lat coordinate system, allowing the user to pass in any xyz point in any radius.
The dependency of plates to CGAL has been removed and such the cmake files have been modified.
