Instead of exposing the RequestInfo object created by the WeatherMgr
return an ID to identify the request. This ID can be later used to
cancel the request if needed. The WeatherProviderService base class
keeps track of the ongoing requests and can map this ID to the
corresponding request
This patch also include the following minor changes:
- Use List instead of ArrayList in API
- Update javadoc to public methods to reflect API changes
- Use UUID random generator in immutable classes to generate the
hashcode rather than relying solely in the hashcode of the builder
object.
