I made a bit refactoring in the whole code.
I add a Downloader class within method remove(String value, String provider, Calendar initDate, Calendar endDate, String period)
MongoDb class has now the option of work in the cloud with mongolab.com. The flag for choose is boolean MONGO_LOCAL = false;
class Downloader added
