Explore the cosmogony

[nlehuby]

We will need a visualization tool (or maybe several tools ?) for our day to day usage of cosmogony.
The purpose of this issue is to gather our needs. Then we may summarize it in the readme of this repo.

Visual coverage by zone type
we want to explore the world on a map, select an zone type and see the existing zones of this type on the map to get an idea of the coverage
a POC has been done in this repo, PR : osm-without-borders/cosmogony_explorer#1

View zone metadata
we want to select a zone and get all its metadata (names in different languages, wikidata id, etc)

All zones containing a point
we want to click the map and see all the zones including the point

Explore the hierarchy
we want to select a zone, and get an idea of its hierarchy :

• see all its parent zones
• see all its direct child zones
• see all its child zones, cascading the hierarchy
• see its other linked zones

Download some zones
we want to select some zones (selecting from the map and/or using the hierarchy) and download them in a GIS friendly format (at least geojson, with metadata as properties).

Quality assurance
We want some dashboard with the coverage tests results described in issue #4
