51c778d2a1 make the convex decomposition sphere covering do a better job of covering shape concavities near the border of the shape by expanding the sampling region by the sphere radius + moving the samples out to better cover the sampling region

a88d570315 add convex decomposition options to leaf node convex hull dataflow node 
+ add a 'max hulls' option to convex decomposition, which functions like 'target num hulls' but can still cap the number of hulls when an error tolerance is specified (target num hulls is ignored when error tolerance is set)

6459e6d93f Make C-array exact predicate calls const-correct, and remove/deprecate confusing 'template VectorType' versions that were making the C-array versions difficult to call. To do the deprecation, the 'template VectorType' has been replaced with explicit inline functions that handle the existing vector types.

4456058517 Make visual studio compile exact predicate code with precise math compile settings, for more consistent performance results, and change to generally compute in double precision for predicates where the 'difficult' cases can be ~50x more expensive to compute. 
Add a TODO to reconsider the INEXACT volatile setting now that we compile with precise floating point math; preliminary testing indicates it should work and be significantly faster in 'difficult' cases.
