 Rewrote bsdf2klems to support tristimulus color and call wrapBSDF.
+Did the same for bsdf2ttree.  Function specifications still gray only.
+
+Reduced a problem where rvu or rholo would be slow to quit when
+run with many processes on a large model or one with a large
+ambient file (taking lots of memory).  We were waiting for
+processes to quit one-by-one, which takes some time for each
+process as it disentangles its shared memory.  We now
+wait for all the processes together, so they can disentangle
+in parallel.  It can still take up to a minute in some cases,
+but not 10 minutes like it was taking before the fix.
+
+Enabled ambient cache value corral for all levels, not just final two.
+This may reduce errors in certain pathological scenes.
