/**
* An annotation that marks a {@code boolean} or {@code Boolean} attribute of a
* modeled class which should be serialized as a DynamoDB BOOL. For backwards
* compatibility with old versions of the {@code DynamoDBMapper}, by default
* booleans are serialized using the DynamoDB N type, with a value of '1'
* representing 'true' and a value of '0' representing 'false'.
* <p/>
* Using this annotation on the field definition or getter method definition for
* the attribute will cause it to be serialized as DynamoDB-native BOOL type.
* Old versions of the {@code DynamoDBMapper} which do not know about the BOOL
* type will be unable to read items containing BOOLs, so don't use me unless
* all readers of your table are using an updated version of the mapper.
