Once done also PR over to Quantuccia itself

Feature request: Allowing for user made calenders - too. Would make it even more powerful - wouldn't it?.

[eddelbuettel]

Pull requests are always welcome, preferably with an initial issue ticket discussing what/how.

[petermeissner]

I will have a look - maybe I understand somehow what is going on.

[eddelbuettel]

Great! It was on my TODO list as well. We should be able to access / instantiate from R such that we can create unions of calendars, plus additions / updates, etc pp -- ie create something more powerful than we currently have in RQuantLib.

But I didn't get to it yet, and the next few weeks are bad. After that, I may have time to come back this.
