[yhoogstrate]

• [x] functional test that changes -m and returns appropriate different results
• [x] use very strict filter in combination with -m and filter results
• [ ] implement following test case and see if, with equal number of reads, 3 fragments can be found:

[===============================================]
[===============================================]
[===============================================]
                         [=============================================]
                         [=============================================]
                         [=============================================]
[======================================================================]
[======================================================================]
[======================================================================]

and enforce 3 fragments as outcome
