The MosaicLayoutBase component is the base class for most composite application layouts, such as FlowLayout and SmartGridLayout.

Layouts using this base class must support padding, vertical and horizontal gaps, when placing their Group's children.

All layouts derived from MosaicLayoutBase automatically get maximize capability as well as some animation effects (eg, when an item is deleted).

The calculateLayoutPositions() function is the key layout function and should be overridden in every sub-class. This is the function that distinguishes one layout from another.
