We have added more examples, and some of them uses the structure of:
````dart
/// ```dart
/// var x = something;
/// ```
/// and then you can also floo the thing
/// ```
/// x.floo(...);
/// ```
````
The following chunks of the same example can now be written as:
````dart
/// ```dart continued
/// x.floo(...);
/// ```
````
Change handling of imports,
and introduce a `top` template different from `none`.
The `none` template gets nothing for free.
The sample must be completely self-contained.
Is triggered by the sample containing a `library` declaration,
because we can't add anything before that.
The `top` template allows top-level declarations,
but does introduce automatic imports and "samples can expect"
code if the sample doesn't contain `import`s.
Is triggered by top-level declarations other than `library`.
Also some restructuring of the code to make this feature easier
to implement.
