[Nodeshot] Interoperability/Synchronizing real testing

[nemesis]

 I wanted to share with you some info about a new feature of nodeshot 
 which makes it interoperable with external services or even other 
 instances of itself.

 In this case, I'm using nodeshot2 as a GeoJSON repository of public 
 wifi hotspot data AND as a synchronizer with an external service which 
 is called CitySDK-Tourism.

 What happens in this case is the following:

  * nodeshot periodically fetches the data from several external 
 services which provide the data
  * it compares with what it has in the database and 
 adds/changes/deletes only what is needed
  * whenever an add/change or delete is performed the external CitySDK 
 service is updated through a RESTful API

 This behaviour is defined in the sychronizer class. It works in a 
 similar way of the "connector" mechanism i described this morning.

 The "interoperability" module is an abstraction layer between different 
 applications that do a similar thing, manage geolocalized data.
 It's a way to make different applications interoperable.

 When I manually launch the command, this is the output I get:
