<LI> Added support for different degree B-splines.
(Note that as the B-spline degree is a template parameter, only degree 1 through 4 are supported.
If higher order degrees are desired, additional template parameters can be easily added in the body of the <U>Execute</U> function inside of <I>PoissonRecon.cpp</I>.
Similarly, to reduce compilation times, support for specific degrees can be removed.)
<LI> Added the <B>--primalVoxel</B> flag to support to extraction of a voxel grid using primal sampling.
<LI> Changed the implementation of the voxel sampling so that computation is now linear, rather than log-linear, in the number of samples.
<LI> Changed the realization of the normal/vector field to use a more compactly supported basis. This gives rise to a smaller system (using less memory and providing a faster solver). Earlier results can be obtained
by setting:<PRE>#define NORMAL_DEGREE 2</PRE> in the file <I>MultiGridOctreeData.h</I>.
