Scramble created (needs visual inspection)

I have created fixed scrambler called one-to-one-mapping.map and it is
serialized under top directory.  Global class has LoadMap function which
initializes two maps: mapFtB, map BtF (frontend to backend and vice
versa). Each map is keyed by Locus and returns another Locus, in
appropriate frontend/backend implementation. Locus is nothing more just
object containing Chromosome and GeneNumber.

I will soon implement the functions accessed by front end to use these
dictionaries by default so front end people don't have to think at it.

I haven't checked the scrambler yet visually, but it is located in
OutputOfTests/Scrambler. The original scrambler is 666 and then there is
loaded scramble 66 from disk. Should be the same. Scrambler 667 should
be the inverse one.
