Initial working Haskell code.
Refactored print to main.
Moved Char to Int transform to main.  Saved about 1.5s.  Run time now 5.55 s.
Revised to process as a big stream and add command line counter for number of digits to process.
Changed analyzeString to use map rather than recursion.  Slowed things down.
Added filtering to the analyzeString.  Much faster, about factor of 2.
Added C version of kata5.
Removed printf statements in favor of out buffer.
Rewrote to implement register-level parallelism. Reduced run time by about 1/3.
