There seems to be an inconsistency in PCL (at least in cturtle...I haven't
checked latest), in that some methods take angles in radians and some in
degrees.  For example, SACSegmentation::setEpsAngle() accepts degrees for
SACMODEL_ORIENTED_PLANE, but radians for SACMODEL_ORIENTED_LINE.  Perhaps there
should be a single convention throughout PCL to avoid confusion?  It's already
caused some headaches around here =)
