VolumeOfConvexEnvelope: Works!

VolumeOfConvexEnvelope has been analysed into various smaller functions and approach is working.
two new files: boundary.?pp
various new functions:
class Tesselation with AddPoint(), TesselateOnBoundary() and GuessStartingTriangle() does the actual tesselation
CreateClustersinWater() will create the repetition of the cluster with correct spacing (unfinished).
GetDiametersOfCluster() calculate the greatest diameter in projection per axis
GetBoundaryPoints() gets the boundary on the convex envelope by projection for a molecular cluster
GetCommonEndpoint() finds the endpoint two lines are sharing
