Implement remaining classes in the Units interface

[bryanwweber]

Abstract

In Cantera/cantera#991, an interface for ThermoPhase and PureFluid classes was implemented in cantera.with_units. This leaves all the other classes to be implemented, such as Kinetics, Interface, Reactor, etc.

Motivation

The request to customize units passed to Cantera functions has been around a long time (see #3). However, implementing all of the classes at the same time was prohibitively time consuming, so we settled on the minimum viable subset of the ThermoPhase class and the closely-related PureFluid class as a test to see how useful this interface will be. This leaves the rest of Cantera's interfaces to be implemented. This enhancement issue will document the remaining interfaces to be implemented, so they can be accomplished individually.
