Feature: Validate Next Visit Date with Closed Dates

[UnconditionedLife]

• Calculate "next visit" date for client receipt then validate against closed dates
  • if the date is same as a "closed date" then subtract a day
  • loop through until an open day is found that is a minimum of 7 days from the current visit.
  • if no open days are found between 7 and 14 days, then add a day to the initial next visit
  • loop through until an open day is found

Looks like the best was to create and store the closed dates is not as an array of all closed dates, but a set of 3 nested arrays: 1) single days 2) days of the week (ie. Sunday) 3) days of week and weeks of the month (ie. (2nd Saturday)

@scott-r Does this make sense to you?

This approach is fine for now, and I will continue to use it as in the existing code. Eventually, we should probably migrate to a library that implements the full complement of recurring date patterns as specified in RFC 5545.
