added calculator to the bottom of the parser combinator and variantType to vcfRecord
added test for genotype and vcfRecord
added sample selection, all genotype fields and vcf and genotype toString functionality
improved parsing of the genotype information
moved genotype attribute construction in to genotype. toString in vcf and genotype returns original string if possible for performance reasons
improved genotype type (homVar,homRef etc) determination functions
added testStart and processing options. Processing options are collected in one class. New options are to exclude filtered and non variant records.
improved vcfRecord unitTest
put samples in normal hashmap in vcfRecord and use original sampleOrder to print the hash in order
changed scala maps in hotspot places to faster java maps
