Hilbert's Epsilon operator and partial functions in Coq (V8.1)

The module ClassicalEpsilon of the new standard library (V8.1 beta) allows us to use Hilbert's epsilon operator.
File Epsilon.v contains the definition of the definite description operator iota, as well as some tactics for dealing with descriptions and partial functions.
A small example is given, comparing partial functions with some (total) implementations.

A3PAT Project (Assisting proof assistants)

This project is devoted to provide proof assistants with more automation: automatic tools should provide the assistant with some trace it will use to build a certified proof term.
