 @abstract
 The `FBOpenGraphAction` protocol is the base protocol for use in posting and retrieving Open Graph actions. 
 It inherits from the `FBGraphObject` protocol; you may derive custome protocols from `FBOpenGraphAction` in order
 implement typed access to your application's custom actions.
 
 @discussion
 Represents an Open Graph custom action, to be used directly, or from which to
 derive custom action protocols with custom properties.
