desc:
This python module is a library used to build planar sketches.
Instead of existing constraints how about constraints that return locations
on objects:
- two circles: c1, c2
- "line tangent to c1 & c2" : 4 locations on each circle
- these would be construction geometry
- user sorts to select the ones they want
- uses these points to build geometry
- how many constraints are currently implemented?
