Matching 4th weekday of month when recurrence started with 5th weekday of month

[mikegleasonjr]

In Google Calendar, when you start a recurrence with let's say the 5th monday of a month, on the next month if there is only 4 mondays it will match the last one. I would expect this library to do the same.

Here's a test case scenario:

moment({ date: 31, month: 2, year: 2014 }) // 5th monday of march 2014
    .recur()
    .every(1).daysOfWeek() // monday
    .every(4) // fifth monday
    .weeksOfMonthByDay()
    .matches(moment({ date: 31, month: 7, year: 2015 })) // aug 31st 2015, 5th monday
    // returns true

moment({ date: 31, month: 2, year: 2014 }) // 5th monday of march 2014
    .recur()
    .every(1).daysOfWeek() // monday
    .every(4).weeksOfMonthByDay() // fifth monday
    .matches(moment({ date: 24, month: 10, year: 2014 })) // nov 24th 2014, 4th monday
    // returns false

Thank you

I created a PR that allows you to match against the last (or second to last, etc) week of the month by day that might help with this use-case. See: /pull/53

You should be able to use simple-recur as an alternative to this project (there are several core bugs described in #85). See https://github.com/jamiter/simple-recur.
I'm waiting on a PR to merge for better documentation for that repo at Swydo/simple-recur#3 -- so until that is resolved you can view better docs at https://github.com/niftylettuce/simple-recur/tree/patch-1#simple-recur in the meanwhile.
