This is related to #15 because [T] is unsized. Ideally, we would be able to have Gc<'gc, [i32]> without any indirection through a Box<[T]>.

The big problem here is that the simple collector expects Gc to have a statically-known size......

This is very important to actually properly implement any real-world use. In theory, arrays could just wrap Vec right now but that's not very elegant.

Add support for garbage collected arrays/vectors
3ec6bd8 
Merges #29 
Closes #16

Right now, access to arrays doesn't trigger write barriers. I need to implement that before I can work on generational
or incremental collection......

The vector API is a little rough around the edges
because `GcVec` doesn't implement `Copy` as all the other `Gc` types do.
See #30 for more details
