Unparameterized field adapter.

A field having an interface similar to that of floats is adapted to LinBox.

Used to generate efficient field classes for unparameterized fields (or hidden parameter fields).

Some fields are implemented by definition of the C++ arithmetic operators, such as z = x*y, for z, y, z instances of a type K. The LinBox field Unparametric<K> is the adaptation to LinBox.

For a typical unparametric field, some of the methods must be defined in a specialization.
