A search unit should implement a `search` method taking a list of keywords as
argument and returning an iterable of search results.
It might optionally implement the following methods and attributes:
- verbose_name (attribute): a nice name to refer to the results of this search unit
in templates. Examples: "COF Members", "K-Fêt accounts", etc.
- result_verbose_name (method): a callable that takes one search result as an input
and returns a nice name to refer to this particular result in templates.
Example: `lambda user: user.get_full_name()`
- result_link (method): a callable that takes one search result and returns a url
to make this particular search result clickable on the search page. For instance
this can be a link to a detail view of the object.
- result_uuid (method): a callable that takes one result as an input and returns an
identifier that is globally unique across search units for this object.
This is used to compare results coming from different search units in the
`Compose` class. For instance, if the same user can be returned by the LDAP
search and a model search instance, using the clipper login as a UUID in both
units avoids this user to be returned twice by `Compose`.
Returning `None` means that the object should be considered unique.

The `search` method produces a dictionary whose keys are the `name`s given in
`search_units` and whose values are iterables produced by the different search
units.
The `uniq_key`s are used to remove duplicates: for instance, say that search unit
1 has `uniq_key = "username"` and search unit 2 has `uniq_key = "clipper"`, then
search results from unit 2 whose `.clipper` attribute is equal to the
`.username` attribute of some result from unit 1 are omitted.
Typical Example:
