Here’s a handy checklist for setting up the connections between two scenes:

1. Create a segue from a button or other control on the source scene to the destination scene.*

2. Give the segue a unique Identifier.It only has to be unique in the source scene
    different scenes can use the same identifier.

3. Create a delegate protocol for the destination scene.

4. Call the delegate methods from the Cancel and Done buttons**

This provides a simple implementation of the 'Chaocipher' encryption
algorithm described at:
http://www.ciphermysteries.com/2010/07/03/the-chaocipher-revealed

Example usage:
import chaocipher
sender = chaocipher.Wheels(CtWheel='QYNBOWTGIRJFEPKLSDMAVZCUXH', PtWheel='JGUACNQLTDHKSOPZFYMXWRVEBI')
receiver = chaocipher.Wheels(CtWheel='QYNBOWTGIRJFEPKLSDMAVZCUXH', PtWheel='JGUACNQLTDHKSOPZFYMXWRVEBI')
cyphertext = sender.encipher("Green eggs and spam")

// iOS: Generating random, non-repeating text
/* 
Selects random words or phrases from an array, and only select any given word/phrase once.

To use it:
-Create a file called words.txt containing a list of words or phrases separated by carriage returns.

-Drag that file into the resources portion of your project, so it will be included in the bundle.

-Call [self buildRandomWordArray] to do the initial setup. That reads the file and populates an array of random indexes.
