/**
* Provides a list of applications and application windows for the Switcher.
*
* This model provides a model two-level iterable data structure. The first
* level of data is effectively a list of applications available for selection.
* Each application can further provide a second-level collection of windows for
* selection. To this end, the model provides the notion of the current
* iterator value within each list, the second iterator value modally
* corresponding to the current iterator value of the first.
*
* The mode of this model is changed by toggling the @p detail_selection
* property. Different iteration calls need to be made by client code depending
* on the state of that property.
