class pyre.algebraic.Ordering.Ordering

This is a mix-in class that traps comparisons

The point is to redirect comparisons among instances of subclasses of {Ordering} to methods defined in these subclasses. These methods then build and return representations of the corresponding operators and their operands.

{Ordering} expects its subclasses to define two class methods: {literal} and {operator}. The former is used to encapsulate operands that are not {Ordering} instances. The latter is used to construct the operator representations
