Query: The classification of Kleinian surface groups, I: Models and bounds   We give the first part of a proof of Thurston's Ending Lamination conjecture.
In this part we show how to construct from the end invariants of a Kleinian
surface group a ``Lipschitz model'' for the thick part of the corresponding
hyperbolic manifold. This enables us to describe the topological structure of
the thick part, and to give a-priori geometric bounds.
