Establishes a global config object for a TypeDispatcher instance, so far with just properties representing comparison tolerances. Begins a "relational" group of functions with basic approximate equality, and an initial primitive ordering comparison. Ensures that methods that depend on properties of `config` will be properly updated when those properties change.
