 /**
  * Method: get_attributes()
  * 	Returns all of the attributes associated with the item. Optionally, the attributes returned can be

  * 	If the item does not exist on the replica that was accessed for this operation, an empty set is
  * 	returned. The system does not return an error as it cannot guarantee the item does not exist on
  * 	other replicas.

  * Parameters:

  * 	$item_name - _string_ (Required) The name of the base item which will contain the series of keypairs.
  * 	$attribute_name - _string_|_array_ (Optional) The names of the attributes. Pass a string for a single value, or an indexed array for multiple values..
  * 	$opt - _array_ (Optional) Associative array of parameters which can have the following keys:

  * Keys for the $opt parameter:
  * 	ConsistentRead - _boolean_ (Optional) True if strong consistency should be enforced when data is read from SimpleDB, meaning that any data previously written to SimpleDB will be returned. Without specifying this parameter, results will be eventually consistent, and you may not see data that was written immediately before your read.
  * 	returnCurlHandle - _boolean_ (Optional) A private toggle specifying that the cURL handle be returned rather than actually completing the request. This is useful for manually-managed batch requests.
