-- | Adds a permission to a queue for a specific <http://docs.aws.amazon.com/general/latest/gr/glos-chap.html#P principal>. This allows for
-- sharing access to the queue.
--
-- When you create a queue, you have full control access rights for the queue.
-- Only you (as owner of the queue) can grant or deny permissions to the queue.
-- For more information about these permissions, see <http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/acp-overview.html Shared Queues> in the /AmazonSQS Developer Guide/.
--
-- 'AddPermission' writes an Amazon SQS-generated policy. If you want to write
-- your own policy, use 'SetQueueAttributes' to upload your policy. For more
-- information about writing your own policy, see <http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/AccessPolicyLanguage.html Using The Access PolicyLanguage> in the /Amazon SQS Developer Guide/.
--
-- Some API actions take lists of parameters. These lists are specified using
-- the 'param.n' notation. Values of 'n' are integers starting from 1. For example,
-- a parameter list with two elements looks like this:  '&Attribute.1=this'
--
-- '&Attribute.2=that'
