finished new geometry, need to debug curvature
added check_error subroutine to check error ie compare u_gr and
u_ex
wrote a subroutine check_error. But, need to find a way to get xi.
added a to-do list
finished debugging MAKE_CHANNEL
Added subroutine crowdy_grid to create grid points.
Merge remote-tracking branch 'origin/crowdy' into crowdy
Added subroutine crowdy_target_points that returns target points in the
stereographic and conformal planes.
Manually applied deleted changes from earlier merge!
Added subroutine check_crowdy_error_tar to check error at target points
for the crowdy example.
Generated grid seems to be fine.
In the process of correcting bugs
checking target calculations, with bugs.
fixed bugs
Merge branch 'crowdy'
