1) Moved various disparate concordance / set splitting functionalities to a new parent tool which works like VariantFiltration (i.e. people can write various modules that fit inside and can be run though it).
2) Fixed up argument parsing in VariantFiltration to use key=value format so we don't accidentally mox up values (like I had been doing).
3) Have indel rod print samples
