Edges of abutments and footings do not always follow the alignment (i.e. not always parallel to bridge). It would be helpful to have an input for skew for each abutment end that allows for independent manipulation. Wingwalls could follow this skew by default, or have a toggle to match abutment end skew.

Currently wingwalls have independent skew values, but those objects to not tie in nicely with abutment bodies when not perfectly aligned.
