vcf_to_sparse.py location for compound het detection

[Naughtoncolin]

I see in the script "DetermineCH.py" that a sparse VCF is required. I also see a reference to "vcf_to_sparse.py" in the arg parse portion of the script. Where can I find this script to convert a vcf to a svcf that is compatible with "DetermineCH.py"?
