Repair interpretation of numeral for BigQ, add a printer (close #2160)
on the way:
- Added a testsuite output file
- Try to avoid nasty unfolding (fix nfun ...) in type of I31.
Idealy we would need a "Eval compute in" for the type of a inductive
constructor
- Stop opening Scopes for BigQ, BigN, BigZ by default
The user should do some Open Scope.
TODO: there's a bug that prevent BigQ.opp to have arg in bigQ_scope
(and so on for other operations), even with some Bind Scope around.
