Command: adds flattery definition options. The options define a single cache setting. To define multiple cache settings, call flatten_value once for each setting.

options by example:

flatten_value :category => :name
# => will cache self.category.name to self.category_name
flatten_value :category => :name, :as => 'cat_name'
# => will cache self.category.name to self.cat_name

When explicitly passed nil, it clears all existing settings
