Include_contig criteria

[brambloemen]

Dear,

Thanks again for the great tool!
I was wondering why the criteria for include_contigs are what they are. Did you benchmark to find out which parameter settings work best?
Are you also considering other binning/clustering methods instead?

Thank you,

Bram
