Detailed Description

AreaAreaIndex allows you to find areas in a given region.

For areas result can be limited by the maximum level (which in turn defines the minimum size of the resulting areas since an area in a given level must fit into the cell size (but can cross cell borders)) and the maximum number of areas found.

Internally the index is implemented as quadtree. As a result each index entry has 4 children (besides entries in the lowest level).
