Cleaned off the examples

The idea is to keep meaningful examples -- A basic example using Surface_mesh with as few parameters as possible -- A seam mesh using Polyhedron_3 with the default parameterizer (MVC) -- A seam mesh using Surface_mesh with the LSCM parameterizer -- An example with a fixed border parameterizer and using different border parameterizer
