almanac: Tools for Working with Recurrence Rules

Provides tools for defining recurrence rules and recurrence bundles. Recurrence rules are a programmatic way to define a recurring event, like the first Monday of December. Multiple recurrence rules can be combined into larger recurrence bundles. Together, these provide a system for adjusting and generating sequences of dates while simultaneously skipping over dates in a recurrence bundle's event set.
