Add Business Day arithmetic

[choptastic]

Per the recommendation from @RomanShestakov, add business day arithmetic.

This will require either accepting a list of business days, or more likely, have a predicate function passed to it which would evaluate whether or not a date is a business day.

This would work with the Modifier in #1 by adding three new date units: business_day and business_week, business_month

• business_day would check each day, only decrementing the counter if the day is actually a business day.
• business_week will increment like a normal week, and then continue incrementing each day until it finds the first business day. Example: Assume today is monday, and next monday is a holiday: 1 business week would be next tuesday, while 2 business weeks would just be two mondays from now.
• business_month will work exactly like business_week, except it increments the month.

In short: business_week and business_month would do valid-business-day checks only at the end, while business_day does one for each day.

Not yet. I haven't had the immediate need in my apps yet for it, so the priority of building it has fallen in lieu of more immediate needs.
