Module Environ

Unsafe environments. We define here a datatype for environments. Since typing is not yet defined, it is not possible to check the informations added in environments, and that is why we speak here of ``unsafe'' environments.

Unsafe judgments.

We introduce here the pre-type of judgments, which is actually only a datatype to store a term with its type and the type of its type.
