* Doctest column name reference
* Document rusqlite assumption on column name reference
And move doctest as a test.
* Document when columns metadata should be extracted.
* Rustfmt doc (wrap_comments)

Replace `Row::get` by `Row::get_checked`,
And rename original `Row::get` to `Row::get_unwrap`.
`Stmt::query_map`, `Stmt::query_map_named`, `Stmt::query_row`,
`Conn::query_row` and `Conn::query_row_named` callback parameter must return a `Result`.
