[cgma-dev] Facet/Cholla engine

[Jane Hu]

Hi, David

I double checked the prototype as well as the code (I don't have a program
suitable to debug), it seems that if your plist is not corresponding to the
tflist and qflist, you may leave it empty. The code should fill the point
list for you.
Unless the points are extra points which are not in the tflist nor in the
qflist.

Can you try it out and see if it works, I am now reading this part of code
to see if coincident points are recognized if you call separately.

Jane
