+The script LocationsParser.rb creates a file named "Locations.json", which contains all the points from the Concertes and Dewey database.
+It parses the .csv files from the Concertes folder and the .json files from the Dewey folder.
+To run it:
+	ruby parser.rb
+
+The main files it uses are:
+	Concertes/20200312_EntreprisesSignaletique.csv which contains the name of the points from the Concertes data
+	Concertes/20200312_EntreprisesCoordonnees.csv which contains the coordinates of the points from the Concertes data
+and
+	Dewey/dewey-maps-markers.json which contains the data of the points from the Dewey data
