/**
 * Set of interactions included in maps by default. Specific interactions can be
 * excluded by setting the appropriate option to false in the constructor
 * options, but the order of the interactions is fixed.  If you want to specify
 * a different order for interactions, you will need to create your own
 * {@link ol.interaction.Interaction} instances and insert them into a
 * {@link ol.Collection} in the order you want before creating your
 * {@link ol.Map} instance. The default set of interactions, in sequence, is:
 * * {@link ol.interaction.DragRotate}
 * * {@link ol.interaction.DoubleClickZoom}
 * * {@link ol.interaction.DragPan}
 * * {@link ol.interaction.PinchRotate}
 * * {@link ol.interaction.PinchZoom}
 * * {@link ol.interaction.KeyboardPan}
 * * {@link ol.interaction.KeyboardZoom}
 * * {@link ol.interaction.MouseWheelZoom}
 * * {@link ol.interaction.DragZoom}
 *
 * @param {olx.interaction.DefaultsOptions=} opt_options Defaults options.
 * @return {ol.Collection.<ol.interaction.Interaction>} A collection of
 * interactions to be used with the ol.Map constructor's interactions option.
