Refactor the basic pipeline

The HumanCytoSNP12 now has parallel calculations for SMP machines. The
principal downstream analysis loop produces:
 - Reduced ranges per copy state;
 - Ranges with coverage score per state;

 Both calculations print data files for Circos/sheet stuff (tsv files).
 Sample names present only on tsv file. Ranges with coverage are intented to be
 used as tiles 2D track data (or similar). Reduced ranges as highlights data
 track.
