+     This algorithm uses the Caesar Cipher algorithm but removes the option to 
+     use brute force to decrypt the message. 
+  
+     The passcode is a random password from the selection buffer of 
+     1. uppercase letters of the English alphabet 
+     2. lowercase letters of the English alphabet 
+     3. digits from 0 to 9 
+  
+     Using unique characters from the passcode, the normal list of characters, 
+     that can be allowed in the plaintext, is pivoted and shuffled. Refer to docstring 
+     of __make_key_list() to learn more about the shuffling. 
+  
+     Then, using the passcode, a number is calculated which is used to encrypt the 
+     plaintext message with the normal shift cipher method, only in this case, the 
+     reference, to look back at while decrypting, is shuffled. 
+  
+     Each cipher object can possess an optional argument as passcode, without which a 
+     new passcode is generated for that object automatically.

     Enhanced Caesar Cipher with shuffled character set for stronger encryption.
     Uses a passcode to generate a unique shuffled key list and shift key.
