 Eliminated unnecessary start-up procedures for rtrace when only ray-casting
 is needed (i.e., no tracing or value output).

+Improved isotropic sampling method in bsdf2ttree using "zipper" approach
+applied in genBSDF.
+
+Added limit to memory used by high-resolution tensor tree BSDFs for
+cumulative cache during MC sampling (rendering).  Limit set to 250MBytes
+per BSDF for standard architectures.
+
+Added -n and -s options to bsdf2ttree to provide some user control
+over super-sampling.
