Merge pull request #4 from AmnonOwed/FixWB_SphereNPE

Fixes NPE on WB_Sphere with default constructor
Fixed JavaDoc errors
Added JavaDocs
Merge branch 'master' of https://github.com/wblut/HE_Mesh2014
Externalized Bernstein polynomial coefficient to WB_Math.WB_Bernstein
Removed shamefully lazy programming from HEC_Box, improving it's
performance hugely.
Recreated javadocs
Removed dependence of 3D triangulation on ProGAL. WB_Delaunay is about
15x faster.
Squashed nasty bug in initialization of WB_AABB
Removed dependence of 3D Voronoi code on ProGAL. Now solely depends on
WB_Delaunay. Only fully closed Voronoi cells are generated, no halfopen
ones. In some cases this may require additional scaffolding points to
generate the desired volume.
Set 3D Delaunay to use Clarkson algorithm in all cases, slightly slower
for low number of points but far more capable of handling degenerate
input.
Added a precision parameter to 3D triangulation and voronoi modules. In
this way both random and degenerate cases can be calculated (with some
experimentation).
Added simple get/set color support: per face, per vertex or per halfedge
(=vertex color per face). Corresponding drawFacesFC, drawFacesVC and
drawFacesHC in WB_Render.
Integrated WB_Render into WB_Render3D. Created WB_DebugRender3D and
WB_SelectRender3D for special purposes.
Removed the HET_Selector and HET_SelectionBuffer. Internal workings were
too dependent on the Processing PGraphics3D "recorder" implementation
and proved too unstable across versions. Functionality was moved to
WB_SelectRender3D and no longer relies on the recorder mechanism.
Added methods to HE_Face, HE_Edge and HE_Vertex to get center and vertex
offset along normal.
Added a few hemesh examples on selection and color
Refactored WB_Distance2D and WB_Distance3D into WB_Distance.
Refactored WB_Intersection2D into WB_Interesection.
Moved data files to separate package
Updated Javolution from 5.5.1 to 6.1.0
Fixed HE_FaceFaceCirculator
Updated Access_Mesh_Elements example
Updated readme to reflect Javolution changes. Also added build-of-the-day.
