The existing relevel() function in "stats" could conveniently be replaced with the
Relevel() from the "Epi" package, which gives some added functionality:

- Moving more than one level up first
- Allowing to combine levels of factors

This functionality is not something specific for epidemiology.

The existing relevel is (almost literally) a subset of Relevel().
