Write an overview of the Constellation code

[jdm]

It's pretty important, and the existing inline documentation is hit or miss. We should write down what we think it does, and then compare that against what it actually does.

@jdm how degree of overview?

Ah, I missed you were assigned by yourself. I felt this is looking for a contributor.

@saneyuki I certainly won't complain if anybody else wants to take a swing at it! I just figured that it was more likely not to be forgotten if I assigned it to myself.

@jdm

Are you working this?
If you have not begun to work this yet, I'd like to try working this.

[jdm]

Please do :)
