Editing Transition probabilities from selected texts

The Somerton Man's code (without the extra line) is 44 characters long. So, if the text is purely random (1/26 chance of each letter appearing) then the probability of attaining this particular string of 44 is (1/26)^44 = 5.51027E-63. This is a good initial comparison.

For transitions that have p=0, corrections to p=0.0001 have been performed to attain a non-zero Markov probability.

HMMER score<ref>ftp://selab.janelia.org/pub/software/hmmer/CURRENT/Userguide.pdf Page 43</ref> is the log (base 2) of Markov probability / null probability (1/26^44)
