Draw a shape on a map and produce a list of all objects held within #47
Description
As a data steward and user of DINA, I wish to draw a polygon on a map to query Sites (or Collecting Events) and be presented with a categorized list of objects held within. For instance, one subset of results would be a list of Sites, another the Collecting Events, and a third the Material Samples referenced/join to those containing Collecting Events. For each of these subsets, I wish to also have the option to download the results as a csv.
