Testable Abstractions in Rails
=============================
In Java or C#, it is common to build abstractions around external
dependencies like Logging or Caching libraries.
The advantages of such abstractions are twofold:
1) They can allow the caller to hide the methods/usage patterns that aren't
relevant to their application.
