/**
* The {@link SendableChooser} class is a useful tool for presenting a selection
* of options
* to the {@link SmartDashboard}.
*
* <p>For instance, you may wish to be able to select between multiple
* autonomous modes.
* You can do this by putting every possible {@link Command} you want to run as
* an autonomous into
* a {@link SendableChooser} and then put it into the {@link SmartDashboard} to
* have a list of options
* appear on the laptop. Once autonomous starts, simply ask the {@link
* SendableChooser} what the selected
* value is.</p>
