Change this to yardoc style:

```ruby
# Returns a normalized version of `datastore['URI']
#
# @return (see #normalize_uri)
# @see #normalize_uri
```

You will then have to add a proper `@return` comment to `normalize_uri` so that it can be copied for the `@return (see #normalize_uri)`.  The `(see` notation allows yard to copy tags so you can keep returns, params, etc DRY and they will just propagate if a change is made lower down.
