OK, I've written and pushed the documentation. I'll try to find 
somewhere to host the generated HTML.

I've also added `SharedSingleton` and renamed `LowLockSingleton` 
to `__GSharedSingleton` for consistency. I *did not* rename 
`ThreadLocalSingleton` to `StaticSingleton` - this will be too 
confusing("aren't all singletons static?").
