@mramato what is the scope for this? Is this something @hpinkos can help us with?

[mramato]

The scope is a bit unknown and it's a pretty big change. I'm okay with @hpinkos working on it, but I need to take the time and figure out exactly what the gameplan is first. I'm hoping to do this sooner rather than later.

I started to look into this and I'm going to start with a pull request to just refactor JulianDate. It's going to follow the same strategy as our other Core types, that is; I will remove most prototype functions, there will be no private variables, all operations will take result parameters, etc..

Additionally, I may remove a few functions that are not being used (for example addHours), and make some functions private or move them to somewhere else (for exmaple getTaiMinusUtc).

Anyone have any thoughts on this before I start? CC @kring @shunter

@mramato can we close this?
