/**
* 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.
* @api stable
