Example of using CGAL to compute the 2D convex hull of some points.
Added GLEW to the list of required and linked against libraries.
Added a bunch of helper functions in preparation for using a GLSL
shader with the terrain mesh reconstruction program.
Created a program to calculate and display the delaunay triangulation
using CGAL.
Now able to collect information about the Voronoi Diagram from
the CGAL Delaunay Triangulation
2D version of program showing voronoi and delaunay triangulation working
with CGAL.
Merge branch 'terrain-reconstruction' into try-cgal

Now the cgal delaunay and voronoi program shows the delaunay triangulation
in 3D
Merge branch 'mesh-sampler' into try-cgal
the cgal delaunay and voronoi diagram program is now reading in the
mesh sample files and successfully creating meshes from them.
Merge branch 'try-cgal'
