working ajax request

I imported my ajax request, but I let the computing of results as is, because I don't really know how do you want to display it. To display the names of cities, you can use this : 
```
for (i = 0; i <= maxPropositionsToDisplay ; i++) {
            if (location[i] == undefined)
                break;
            propositions += ('<p>' + location[i].name +'</p>');
        };
```
