/**
  Represents a request to the Facebook Graph API.


 `FBSDKGraphRequest` encapsulates the components of a request (the
 Graph API path, the parameters, error recovery behavior) and should be
 used in conjunction with `FBSDKGraphRequestConnection` to issue the request.

 Nearly all Graph APIs require an access token. Unless specified, the
 `[FBSDKAccessToken currentAccessToken]` is used. Therefore, most requests
 will require login first (see `FBSDKLoginManager` in FBSDKLoginKit.framework).

 A `- start` method is provided for convenience for single requests.

 By default, FBSDKGraphRequest will attempt to recover any errors returned from
 Facebook. You can disable this via `disableErrorRecovery:`.

 By default, non-batched FBSDKGraphRequest instances will automatically try to recover
 from errors by constructing a `FBSDKGraphErrorRecoveryProcessor` instance that
 re-issues the request on successful recoveries. The re-issued request will call the same
 handler as the receiver but may occur with a different `FBSDKGraphRequestConnection` instance.

 This will override [FBSDKSettings setGraphErrorRecoveryDisabled:].
