* <p>
* Given variant tracks, it replaces the reference bases at variation sites with the bases supplied by the ROD(s).
* Additionally, allows for one or more "snpmask" VCFs to set overlapping bases to 'N'.
* Note that if there are multiple variants at a site, it chooses one of them randomly.
* Also note that this tool works only for SNPs and for simple indels (but not for things like complex substitutions).
* Several important notes:
* 1) if there are multiple variants that start at a site, it chooses one of them randomly.
* 2) when there are overlapping indels (but with different start positions) only the first will be chosen.
* 3) this tool works only for SNPs and for simple indels (but not for things like complex substitutions).
* Reference bases for each interval will be output as a separate fasta sequence (named numerically in order).
