Comment (by cheuberg):
My reasoning for having it as a function as opposed to methods on RIF
elements where:
1. There are methods `.min` and `.max` performing the operation for the
minimum and maximum of two elements
2. I think that the functions as proposed here are easier to use, e.g.,
the infinity norm of a vector of real intervals could simply be written as
`max_RIF(abs(r) for r in v)`.
Therefore, I felt that having those as functions in the module `real_mpfi`
(and not importing those in the global name space) is appropriate.
