the default bin size of batch --method wgs

[deb0612]

Dear sir, I tried to apply "cnvkit.py batch Sample1.bam -n Control1.bam -m wgs -f hg38.fasta --annotate refFlat.txt" to my WGS data. When use gencode.v37.annotation as target bed, we got very large segment. However, we need to smaller the segment size. We would like to know what the default bin size.
