Demonstration Example of Hyperframe of Spatial Data

This is an artificially constructed example of a hyperframe of spatial data. The data could have been obtained from an experiment in which there are two groups of experimental units, the response from each unit is a point pattern Points, and for each unit there is explanatory data in the form of a pixel image Image.
