Gender Snippets

/*This snippet will find a patients's gender if it is recorded.
The logic behind this code is to present any formal recording of gender with an option
to assume the patient sex is the gender if gender is not formally recorded. The decision
to include the sex as gender will need to be made by understanding the context of the
reporting, including any formal specifications provided by the reporting body. */
