Settings the day of week and day of month.

[treadon]

If both fields are restricted (for day of month and day of week) a cron should match for either case, as per the cron man:

 Note: The day of a command's execution can be specified by two fields --
 day of month, and day of week.  If both fields are restricted (ie, are
 not *), the command will be run when either field matches the current
 time.  For example, ``30 4 1,15 * 5'' would cause a command to be run at
 4:30 am on the 1st and 15th of each month, plus every Friday.

However, in a test with the following expression:

0 16 4 * fri *

The expected behavior is every Friday OR every month on the 4th.

However, when running this, it matches if it is a Friday AND it is the forth: here is sample output:

Next: Fri, 04 Nov 2016 16:00:00 +0000 Last: Fri, 04 Mar 2016 16:00:00 +0000

Great library otherwise.

Please dont change the week + day-of-month into "OR" combination. "AND" is very useful in below practical scenario:

"First sunday of month" 0 0 1-7 * 7

This is not possible in the "OR" condition.

you must use two cron expression for this

0 16 4 * * * 0 16 1-7 * fri *
