    # Generates an association using the current build strategy.
    #
    # Arguments:
    #   name: (Symbol)
    #     The name of the factory that should be used to generate this
    #     association.
    #   attributes: (Hash)
    #     A hash of attributes that should be overridden for this association.
    #
    # Returns:
    #   The generated association for the current build strategy. Note that
    #   assocaitions are not generated for the attributes_for strategy. Returns
    #   nil in this case.
    #
    # Example:
    #
    #   Factory.define :user do |f|
    #     # ...
    #   end
    #
    #   Factory.define :post do |f|
    #     # ...
    #     f.author {|a| a.association :user, :name => 'Joe' }
    #   end
    #
    #   # Builds (but doesn't save) a Post and a User
    #   Factory.build(:post)
    #
    #   # Builds and saves a User, builds a Post, assigns the User to the 
    #   # author association, and saves the User.
    #   Factory.create(:post)
