    # Why `.decorate`?  In my tests for Rails 5.2, I'm not able to use the prepended nor included
    # blocks to assign a class_attribute when I "prepend" a module to the base class.  This method
    # allows me to handle that behavior.
    #
    # @param base [Class]
    # @return [Class] the given base, now decorated in all of it's glory
