Explanation of SVbenchmark's --normshift option

[TimD1]

Hi @nhansen,

I can't tell from the documentation exactly what the --normshift option does. It seems that --maxdist ensures two variants are near one another, --normsizediff ensures they're approximately the same length, and --normdist ensures that they contain approximately the same edits to the reference sequence. Is --normshift similar to --maxdist, and ensures that the location of one variant is not too far from the other, but this time relative to the SV's total length?

Thanks in advance for the clarification, Tim
