> The QuadTreeNode has the concept of a data container per node in the QTree, but I'd like
to extend this to a general SIS spatial data type. This would in part be motivated by e.g.,

> Any measurement we take in Earth and environmental sciences, although this is often ignored,
has a spatio-temporal reference. A spatio-temporal reference is determined by (at least) four
parameters:
> 1. geographic location (longitude and latitude or projected X,Y coordinates);
> 2. height above the ground surface (elevation);
> 3. time of measurement (year, month, day, hour, minute etc.);
> 4. spatio-temporal support (size of the blocks of material associated with measurements;
time interval of measurement);
