Create the Type.Inference module which handles type inference from
...
start to finish. Give it a Module and it returns a dictionary mapping
top-level values to types.

Fix error in generalization in which some variables would escape their
...
rank. Problem was that young variables were not all being marked as
young.
This resolved a soundness issue described in the post on
"How OCaml type checker works".
