It would be nice if the generated code had no `import` statements (in favor of `using`.

It would be nice if the resulting code used `using` rather than `import`.

So instead of generating
```
import ProtoBuf as PB
```
generate
```
using ProtoBuf: ProtoBuf as PB
```

One problem with `import` is that it's easy to accidentally overwrite a packages symbol without realizing you did it.  For example to extend a function with a new method.
