Add new AutoScaler and CustomScalerBase classes

[andrewlee94]

Depends on #1436

Summary/Motivation:

This PR adds a draft of the new Scaler classes along with some general utility functions for the new scaling interface. I have generally created new functions even if older ones existed to make a clean break from the older API and assist with backward compatibility.

Draft Documentation: Initial Outline of Documentation for Scaling Tools.docx

Changes proposed in this PR:

• New ScalerBase class
• New AutoScaler class
• New CustomScalerBase class
• Utility methods for manipulating scaling suffixes
• Demonstration tests of new methods on Gibbs reactor
