Added NURBS_Surface class, with some definitions.
Merge branch 'master' into development
Merge branch 'development' into terrainimprove
Renamed NURBS_Surface to NURBSSEV (NURBS Surface Encapsulated Volume)
Added Intersection check (&&)
Added planned functions for TerrainGenerator and Simplexnoise
Added PhysObject class, minor modifications in Simplexnoise
Added code for 4D simplex noise
Added gradients and simplex corners for 4d noise
Changed simplexnoise interface, added methods for changing frquency and octaves
Added constructor definitions for NURBSSEV, added NURBSSEV.cpp to makefile, added PointVector class (used for points and vectors)
Added function that (somewhat) evenly distributes points on a sphere
Merge branch 'terrainimprove' into development
Merge branch 'nurbsimplement' into development
Added some definitions to PhysObject
Modified Makefile
Fixed Simplexnoise array initialization problems (no longer requires c++0x)
Added all current files to makefile, added cross and dot product to PointVector
Updated NURBSSEV definitions
Re-wrote arithmetic functions in PointVector to prevent memory leaks, added static versions of all functions.
The NURBSSEV mesh can now be calculated and displayed. Added some more definitions to NURBSSEV
