sharing domains

Most, if not all the issues I have with sharing have to do with edge conditions. In previous implementations this was avoided by sharing at the realm level, where realms were non-overlapping collections of roles.

We can do the same in CompStrm. Under the root, Data, we can define various domains, each with its own access and sharing rules. Then no more edge conditions--a page may not be under two pages in different domains. Applicative context and references can still cross domains, so we will not loose much.

Feeling better!
