Csec and Lineweb

@ steve - thanks, I'm glad it will be useful!

@ Will - yeah it is kind of related to Network since it involves a gridwork of curves like Network uses. But yeah this command is focused on generating curves (or lines or points) and not a surface like Network is. I'm not really sure how I could combine it with Network without making the command more complex with more options and modes within it.
