2.1.1.3
  Adding option -T

15/07/2013 read2SNPs_2.1.0.0:

    1/ improves speed and memory (thank to  Salikhov, Kucherov and Sacomoto work)
    2/ adding post-treatment scripts
    3/ by default: keep the low complexity SNPs.

29/07/2013 read2SNPs_2.1.1.0:

    script run_read2SNPs.sh can now be called anywhere
    bubbles are now of length 2k-1 instead of 2k+1 before extensions. This improves the precision/recall

    Bug fix (consequence of bubbles of length 2k-1)
2.0.5.9
 - integrating the gustavos changes
2.0.5.8
2.0.5.7
 - verify the branching of the two extreme kmers of each bubble
 - kissreads ranks swrt qrt(Xi2,sum) 
2.0.5.4
 - symetrise the branching extremities test of the bubbles
2.0.5.3
 -  fixes a (last ?) small bug with the ranking function & enhance the pipeline avoiding odd k values
2.0.5.2
 - removes useless output and proposes a full pipeline with a use case
2.0.5.1
 -fixes a bug with the kissreads ranking function
2.0.5 (2013 04 11)
 - validated version about branchings
2.0.4 (2013_04_10) 
 - simplified code for the detection of branching kmers during SNP detection
2.0.3 (2013_04_08)
 - option b means print branching snps
 - by default, only non branching snps are printed (tests of branching are done in both directions)
2.0.2: (2013_04_05)
 - adding option -C
 - clarifying the -h message

2.0.1: initial version
