- remove custom runner (deprecated) use miniTest::spec and after_run instead
- instal gem minitest 5.3.1 and minitest-ci 3.0.3 to use it
- generate Xunit report

- rectangular selector was able to detect clones but not sequences

- button added to list_menu

This test is a real recombination and should be properly segmented

No reason to have separate (hard-coded) constants for delta_max. Now we just have one.

Put tests specific to segmentation in testSegment()

Several features added (from CRAC's should-to-tap):
- Can ignore any amount of whitespaces
- Can require to match exactly a pattern (no regex: special characters are protected)

- Drag and drop possible to bring back undisplayed time/point inside

- possibilty to put away a point by drag and drop over label "others"
- TODO a menu to take them back

Side effect: no 'clones.vdj.fa' and 'seq/*' files are produced.
The 'vidjil.data' file is still produced.

This is the main Vidjil output (as a fasta file): representatives of the clones, ready to be processed by other tools.
Until now, this output was on stdout and (partially) in out/seq/*

var t was the current position inside the time_order array
now var t is just the current time and time_order is used only to draw graph

js : change method to compute min_size and precision, the min_size depends of the normalization, so we need to recompute min_size and precision value after each normalization

Vidjil should not be used to segment reads.

It could be nicer with python argparse :)

so we need to call update_normalization if the time_order change or if the clone_size change
