Jonathan Westhues b293c0ef41 Split the Entity and Constraint classes into Xxx and XxxBase, with 
the fundamental geometric stuff in XxxBase. Next I hope to make the
constraint solver use only the XxxBase types.

Jonathan Westhues 984956cbc7 Add a constraint to make line length equal arc length. That's quite 
tricky; can't just use the dot product, since that blows up when
you cross pi radians. A gear shift approach, use either sin or cos,
same kind of thing as the 3d-parallel constraint.

And report a NaN constraint as unconverged, of course.

Jonathan Westhues bf4de993cb Split constraint.cpp into two files: one for building the 
constraint structures based on user input, and one for generating
equations from the constraints.
