The simple means of removing processed letter seemed obvious, just
find the current letter and ROT to the new one, but that did mean that
no letter can represent itself, historically bad.

So, fix that: At the same time are two permutations available, one
that became the other at the pleasure of a key segment. The fix was to
do as before but with both available permutations instead of just the
one. To come out right, the order of substitution switches dependent
of whether encryption or decryption is involved.

Before, the high frequency of "e" in plaintext meant that it would be
the lowest frequency in ciphertext, but with double substitution there
is no such signature.

I also added selection of the two offsets on the face of the page and
making the new one "0" means effectively turning it off.

I am trying to furthermore, keep the beast as simple as possible so
that it leaves no effect other than the desired statistically flat
distribution curve.

Colorful Diary Pizza is out there. Have fun with all those
tantalizing comments you might want to make and reserve for
yourself...unless you never learned to use a computer in a security
oriented manner and you are yet are daunted by JavaScript. Looking at
the larger than normal code, I was also in search for dietary pizza
but that was unavailable. It's turtle slow but terrapin tough.
