Names for this factory, including aliases.

Example:

  factory :user, :aliases => [:author] do
    # ...
  end

  FactoryGirl.create(:author).class
  # => User

Because an attribute defined without a value or block will build an association with the same name, this allows associations to be defined without factories, such as:

  factory :user, :aliases => [:author] do
    # ...
  end

  factory :post do
    author
  end

  FactoryGirl.create(:post).author.class
  # => User
