Standalone AA implementation ready for review

You have a lot of search space to cover, so before doing a 
systematic search that requires a lot of time I suggest a quick 
random sampling of the search space. If there are significantly 
wide performance inefficiencies you will hit them in less than 
one hour of tests. Such approach is sometimes missed even by 
professional engineers :-)

I have already given a link to a game solver that uses 
associative arrays a lot.

Then, this is my currently "best short solution" of one of the 
Shootout benchmarks that stresses only hashing. The input data 
comes from the Fasta benchmark (just use the Python or C++ Fasta 
code if you want the test data):

I have few other benchmarks.
