Neurotic changes
Given a finite extension L/K of the fraction field of a discrete
valuation ring, we say L/K is 'unramified wrt A' instead of just saying
that it is 'unramified'. There are two reasons:
1. There may be more than one dvr whose fraction field is K
2. We already have a notion of an unramified ring map and we do not
want the reader to think we are asking K ---> L to be unramified as a
ring map...
Yes, this is probably not necessary...

Level lowering in Epp's proof
The most intricate part is now done. Tried to make the mized
characteristic part of the proof resemble the characteristic p
part of the proof. It is clear that it works, but it is kind of
annoying to write down.

Get separable extension in the first case of Epp's argument
Of course this doesn't work if you started just taking a pth
root out of a uniformizer of the base dvr
