make_hinge_quaternion(point_on_line, direction_unit_vector, rotation_angle)

This make a quaternion that will rotate a vector about a the line that passes through the point ‘point_on_line’ and has direction ‘direction_unit_vector’. The quat rotates ‘rotation_angle’ radians. The quat is meant to be multiplied by the vector [x y z 1]
