==============

This module contains the base class for a network element.

Strictly, a network element is any callable which accepts an immutable
.info.SpectralInformation object and returns a .info.SpectralInformation object
(a copy.)

Network elements MUST implement two attributes .uid and .name representing a
unique identifier and a printable name.

This base class provides a mode convenient way to define a network element
via subclassing.
