pull request for issue #387

Hi everyone, I implemented the features I needed, as I described in the issue.

This would be excellent to have merged if possible - just implemented my own (less good) solution here #398.

Having this would really expand the ability to use this library in my opinion.

@davidgoli is there any chance we could have this merged?

The main draw back with this approach is that lists of times are not supported though that may be intentional.

For example in the list case you would have to list all permutation for this to work

// Invalid
every day at 9:00 and 11:30 => RRULE:FREQ=DAILY;BYHOUR=9,11;BYMINUTE=0,30
// valid
every day at 9:00, 9:30, 11:00 and 11:30 => RRULE:FREQ=DAILY;BYHOUR=9,11;BYMINUTE=0,30

Personally, I think it's reasonable to limit this to one hour time combo to prevent confusion

Any updates?

This diff is too large. Please revert all lint-style formatting changes (semicolons, quotes around property names, reformatting etc), rebase on master, and re-push. Thanks!
