The universe constraint manager is more flexible now.
We don't need to start with a huge universe U >= 512.
We can start small, and increase it on demand.
If module mod1 needs it, it can always add
universe U >= 3

The parser had a nasty ambiguity. For example,
f Type 1
had two possible interpretations
(f (Type) (1))
or
(f (Type 1))
To fix this issue, whenever we want to specify a particular universe, we have to precede 'Type' with a parenthesis.
Examples:
(Type 1)
(Type U)
(Type M + 1)
