Request and ResultSet methods

-----------------------------

Those are methods you'll find on both request objects and on

repository session.

Request methods

~~~~~~~~~~~~~~~

`URL handling`:

* `build_url(*args, **kwargs)`, returns an absolute URL based on the

  given arguments. The *controller* supposed to handle the response,

  can be specified through the first positional parameter (the

  connection is theoretically done automatically :).

`Data formatting`:

* `format_date(date, date_format=None, time=False)` returns a string for a

  date time according to instance's configuration

* `format_time(time)` returns a string for a date time according to

  instance's configuration

`And more...`:

* `tal_render(template, variables)`, renders a precompiled page template with

  variables in the given dictionary as context

Result set methods

~~~~~~~~~~~~~~~~~~

* `get_entity(row, col)`, returns the entity corresponding to the data position

  in the *result set*

* `complete_entity(row, col, skip_bytes=True)`, is equivalent to `get_entity` but

  also call the method `complete()` on the entity before returning it
