-/**
- * A class to store Frequency-rules in. Will allow a easy way to find the
- * last and next occurrence of the rule.
- *
- * No - this is so not pretty. But.. ehh.. You do it better, and I will
- * gladly accept patches.
- *
- * Created by trail-and-error on the examples given in the RFC.
- *
- * TODO: Update to a better way of doing calculating the different options.
- * Instead of only keeping track of the best of the current dates found
- * it should instead keep a array of all the calculated dates within the
- * period.
- * This should fix the issues with multi-rule + multi-rule interference,
- * and make it possible to implement the SETPOS rule.
- * By pushing the next period onto the stack as the last option will
- * (hopefully) remove the need for the awful simpleMode
