// createSampleGeneticAnalyses.go is a utility used to create the sample genetic analyses.
// These are analyses which are shown in the GUI to demonstrate what genetic analyses look like.
// These analyses are stored in the /internal/genetics/sampleAnalyses folder.
// You must add 2 raw genome files to this folder before running the utility: Person1RawGenome.txt and Person2RawGenome.txt
// I added some cystic fibrosis variants to my raw genome files so that the sample analysis would show a non-zero offspring risk.
