~Bug description~ ~line_to_line_residual is the DQ_Kinematic was not pesent. Comment seem to reference to line_to_point_residual instead.~

~propose fix maybe in #47~

Edit by @mmmarinho for clarity:

Bug

There is no line_to_line_residual accessible through the Python API.

Cause

There are two wrappers for line_to_point_residual one in L62 and one in L64. Probably it was a typo, and given that pybind11 doesn't complain about redefined wrappers (at least not in this situation), it has been around for a long time.

@qlin960618 Thanks, if the CI passes you can check the new ‘—pre’ version and it should be working.
