Subject: 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.
