  * Clean up RSpec suite to not use 'should'
  * Use create_list in step definitions
  * Syntax methods that deal with ORM interaction (attributes_for, build, build_stubbed,
    and create) now accept a block that yields the result. This results in a
    more convenient way to interact with the result than using Object.tap.
  * Standardize deprecation warnings
  * Update transient attribute syntax to use blocks instead of calling ignore on
    each attribute declaration
  * Parents can be defined after children because factories are evaluated when
    they're used; this means breaking up factories across multiple files will
    behave as expected

    handful of methods for a more clearly defined API

    (fixes some issues with dependencies being loaded too early) (thanks to
    Josh Nichols)

    and Josh Owens)
