Documentation - TySplines

[tyFlow]

Those are Max-added rollouts, not ones I've created (they're added to all spline-esque objects automatically). Their settings are outlined in the Max documentation, so I'm not too worried about covering them in my own docs

Also the rendering rollout should generally just be ignored because the tySplineMesher is a million times superior to the incredibly slow meshing methods used by the default Max spline mesher.
