US recessions

Displays US recessions from 1900 - 2014 listed here: nber.org/cycles.html
Unix timestamp generated using this service: unixtimestamp.50x.eu/. For beginn/end of recession always taken the 15th day of the particular calendar month.
Tradingview has a bug by using unix timestamp: I had to add "000.0" to each generated timestamp to display the date in the tradingview correctly. Once the bug will get corrected, this cript will no more work!
The bug is described here: getsatisfaction.com/tradingview/topics/unix-timestamp-in-pinescript?utm_source=notification&utm_medium=email&utm_campaign=new_reply&utm_content=topic_link

Unfortunately tradingview does not allow to display any (forecasted) recession into the future and or with later dates then 1900! This is disappointing.

NOTE: I can not code at all. PLEASE modify this script as much as you like. Particular would be helpful, if:
- there is only one background colour to edit
- there are tickboxes, where you can deselect the particular recession with titles of such recessions
- perhaps electively be able to display the title of the particular recession directly on its background within the chart
