13418	Natural keys documentation: 1) tuple requirement in serialization is missing, 2) use unique_together	hunajakippo	nobody	"As discussed {1} I propose following changes to natural keys (de)serialization documentation {2}:

1) mention requirement to use tuple also in natural keys/serialization section (currently this is only mentioned in deserialization). 
 * For example: ""A natural key is a tuple of values that can be used to uniquely identify an object instance without using the primary key value""

2) in the example model define Person first_name and last_name as unique_together.
 * For example: ""class Meta: unique_together = ((""first_name"", ""last_name""),)""
