/* \brief Simple r-tree example
This example will show you how to manage 2 dimensional data, using an
r-tree index.
The example will insert a couple of rows containing rectangle data which
will be put into an r-tree.
The example will then perform a series of queries to retrieve the data
that meet specific criteria.
