TCLP

This release added the possibility to add type aliases. That is, to declare and use names as shortcuts for types in type declarations.

The speed of type inference has been improved for large programs with
a lot of mutually recursive predicates. TCLP now tries to type check
prolog files for modules that don't have .typ files. The error messages
have been updated so they can be understood by Emacs in a compilation
buffer.

A cache system was implemented in order to speed up the initialization of TCLP. This release also contains two bugfixes: it correctly prints errors of typeof declarations, and prints names correctly when encountering an error with --option nodefault.

DCG expansion has been added. TCLP now prints the
type of variables when finding an error in a clause.

In this release, a speed improvement was achieved
thanks to the elimination and the simplification of various
type constraints. There were also some bugfixes, both in
libraries and in the type checker.
