The web site http://nominatim.openstreetmap.org/ offers a search service http://nominatim.openstreetmap.org/search/ that when given
a street name will return occurrences of such street name, each one with characterizing information such as longitude and latitude.
In this challenge, you should write an expression that returns a collection of location using for example a pair whose key is the description
of the location and the value its latitude and longitude.
For example we did a query with Rue de Paris and we selected two results and they are as follows:
We suggest to ask the server to return JSON.
To specify the format, put 'jsonv2' to 'format' in the query.
You can also define a limit to the number of results using the parameter 'limit' and put it to '10'.
