Visualize your crontab!
Currently, you can see the next occurrences of a given cron expression.
$ pry
> cv = CrontabVis.new # you can supply :anchor_time, which can be any timestamp like `Time.parse('2014-01-01')`
> cv.next_occurrences('30 * * * *', limit: 1.month)
#=> a list of timestamps when this cron expression will trigger over the next month
Notes:
- Some experimentation with a web server based visualization using vis.js.
