Changed constraint boundaries for gap variables. Changed lower score threshold in pathfinder to 1.
removed constraints on insert size in LP program. Works better since parameter space is bigger.
Updated objective function in LP to weight for contamination ratio
Added comtamination ratio to parameters and now, LP is forbidding PE oriented onservations larger than mean + 6*stddev
Fixed introduced bug. Observations are allowed to bee too large for initial path order.
Removed print to stdout statements to. This branch is now ready to be merged into both develop then master.
Added parameter --no_score to deactivate scaffolding with "larger contigs" using statistical measures. This flag will make BESST only search and join contigs with the pathfinding framework
fixed an indtoduxed bug: two large contigs can now also be joined in pathextension algm
added parameter --no_score to deactivate statistical testing
Done with implementing LP for paths. added a couple of parameters:
--filter_contigs <int> (filter out contigs smaller than a given value)
--no_score (solve scaffolding only with LP paths)

Merge branch 'feature/LP_paths' into develop
Fixed small bug in output (previously N50 was named LG50 and L50 was named NG50)
