Reformulate the penalty factor to not include fiber segment information
Fix the fiber intersection algorithm in conjunction with updates to the local operator. Information from adjacent fiber segments with element intersections are not needed anymore. The algorithm now explicitly allows fibers ending exactly at a grid intersection.
Make intersection algorithm allow for fibers that begin at a grid intersection
Add test test-fiber-intersection.cc for verifying the fiber intersection algorithm
