Freq Hourly

[agentgas]

Hi,

I was wondering if Hourly Frequency will be possible one day ?
For now all we get is Valid FREQ with things like:

rrule = "FREQ=HOURLY;INTERVAL=12"

gives:

RRule::InvalidRRule (Valid FREQ value is required)

This can be closed as it was resolved by PR #66. #73 adds support for these frequencies to the humanizer.
