OpenNURBS surface EvNormal() was failing when at surface singularity but not on corner of domain. If fails and at singularity this wrapper will now reevaluate at domain corner.Also made IsAtSingularity()
11:56.01 Notify public and added tolerance input parameter. Also created rendition of IsAtSingularity() that takes ON_2dPoint instead of u,v.

20:22.52 raj12lnm hi.
20:23.33 raj12lnm can anyone tell me regarding rt_constraint_internal ?
20:23.45 raj12lnm I digged in the code
20:24.02 raj12lnm this is "primarily" allocated twice in the code.
20:24.22 raj12lnm And both times the data is assigned as a predefined values.
20:27.17 raj12lnm can Somebody point me to a brlcad document on the uses of constraints ?
20:27.18 raj12lnm for instance in mk_constraint(...) the last argument expr is unused and it assigns same paramters on every call of mk_constraint ?

21:28.49 hcurtis brlcad: Checking in
21:37.12 hcurtis I was told that 99% of the time, I don't need to install BRL-CAD. Does this mean that instead of installing, I need to run binaries that are in the brlcad/.build/bin directory, or does it mean that I don't need to do anything (besides maybe build)?
21:49.19 starseeker hcurtis: um. If you're testing software, you need to run it - the binaries in the build directory are fine for that purpose without needing to install them
21:49.49 starseeker raj12lnm: constraints aren't mature in BRL-CAD as yet
21:51.51 hcurtis starseeker: Thank you.

23:50.17 hcurtis Update: I am trying to have my dynamic allocation program use a BRL-CAD library API instead of the standard library. A mistake I made was to try to read and understand material that seemed informative but turned out to be beyond my skill level. I thought I was doing something "good" for my development as a programmer, but I realize now that it was inefficient.
23:51.05 hcurtis Fortunately, however, I have managed to find information that is more appropriate for an entry-level coder like me. Maybe now I can make more progress.
23:52.12 andrei__ shouldn't you keep the logs on your devlog ?
