// Adds a permission to a queue for a specific principal (http://docs.aws.amazon.com/general/latest/gr/glos-chap.html#P).
// 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 Shared Queues (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/acp-overview.html)
// in the Amazon SQS 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 Using The Access Policy Language (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/AccessPolicyLanguage.html)
// in the Amazon SQS Developer Guide.
//
//  Some API actions take lists of parameters. These lists are specified using

// This means you can't extend the timeout of a message in an existing queue

// visibility timeout, see Visibility Timeout (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/AboutVT.html)
// in the Amazon SQS Developer Guide.)
//
// For example, let's say you have a message and its default message visibility
// timeout is 5 minutes. After 3 minutes, you call ChangeMessageVisiblity with
// a timeout of 10 minutes. At that time, the timeout for the message would
// be extended by 10 minutes beyond the time of the ChangeMessageVisibility
// call. This results in a total visibility timeout of 13 minutes. You can continue
// to call ChangeMessageVisibility to extend the visibility timeout to a maximum
// of 12 hours. If you try to extend beyond 12 hours, the request will be rejected.
//
// There is a 120,000 limit for the number of inflight messages per queue.
// Messages are inflight after they have been received from the queue by a consuming
// component, but have not yet been deleted from the queue. If you reach the
// 120,000 limit, you will receive an OverLimit error message from Amazon SQS.
// To help avoid reaching the limit, you should delete the messages from the
// queue after they have been processed. You can also increase the number of
// queues you use to process the messages.
//
// If you attempt to set the VisibilityTimeout to an amount more than the maximum
// time left, Amazon SQS returns an error. It will not automatically recalculate
// and increase the timeout to the maximum time remaining.
//
// Unlike with a queue, when you change the visibility timeout for a specific
// message, that timeout value is applied immediately but is not saved in memory
// for that message. If you don't delete a message after it is received, the
// visibility timeout for the message the next time it is received reverts to
// the original timeout value, not the value you set with the ChangeMessageVisibility
// action.
