Ordered normed spaces

In this file, we define classes for fields and groups that are both normed and ordered. These are mostly useful to avoid diamonds during type class inference.

A NormedOrderedAddGroup is an additive group that is both a NormedAddCommGroup and an OrderedAddCommGroup. This class is necessary to avoid diamonds caused by both classes carrying their own group structure.
