"""Requests the creation of a new applet.
An applet is identified by its name and an optional list of groups that
represent a path (nested groups). If ``group`` is a string, it
corresponds to a single group. If ``group`` is ``None`` or an empty
list, it corresponds to the root.
``command`` gives the command line used to run the applet, as if it
was started from a shell. The dashboard substitutes variables such as
``$python`` that gives the complete file name of the Python
interpreter running the dashboard.
If the name already exists (after following any specified groups), the
command or code of the existing applet with that name is replaced, and
the applet is shown at its previous position. If not, a new applet
entry is created and the applet is shown at any position on the screen.
If the group(s) do not exist, they are created.
If ``code`` is not ``None``, it should be a string that contains the
full source code of the applet. In this case, ``command`` is used to
specify (optional) command-line arguments to the applet.
This function is called when a CCB ``create_applet`` is issued.

Client control broadcasts (CCBs)
********************************
Client control broadcasts are requests made by experiments for clients to perform some action. Experiments do so by requesting the ``ccb`` virtual device and calling its ``issue`` method. The first argument of the issue method is the name of the broadcast, and any further positional and keyword arguments are passed to the broadcast.
CCBs are used by experiments to configure applets in the dashboard, for example for plotting purposes.
