Centralized means of determining processing and aspects
Centralized means of determining processing and aspects

* The #_aspects method centralizes the logic for determining which aspects
  are created.  It currently mimics the previous behavior by deferring to a
  virtual attribute of the same name and a class configuration option, but
  it can easily be completely overridden by custom logic.
* The #processing method centralizes the logic for determining which
  processing steps are required.  It too defers to a virtual attribute of
  the same name.
