Proposal: `namedTypes*` to `sharedTypes*`, `@shouldExport` to `@export` or `@public` or `@published`

[MikeChongCan]

Two naming suggestions.

namedTypes* to sharedTypes*

named sounds ambiguous. This kind of type is shared between different modules/files.

@shouldExport to @export or @public or @published

shouldExport looks a bit lengthy. Can we simplify it?

The first looks good to me. I have doubt about @export, @public though. It may be confused with TypeScript keywords.

These tags would only be strings instead of identifiers in the runtime. Even if it has conflicts with TypeScript keywords, it won't affect anything?

In addition, export in TypeScript has similar meaning with @export in the context of ts-gyb.
