#include <FWCore/Utilities/interface/EDGetToken.h>
Description: A Token used to get data from the EDM
Usage: A EDGetToken is created by calls to 'consumes' or 'mayConsume' from an EDM module. The EDGetToken can then be used to quickly retrieve data from the edm::Event, edm::LuminosityBlock or edm::Run.
The templated form, EDGetTokenT<T>, is the same as EDGetToken except when used to get data the framework will skip checking that the type being requested matches the type specified during the 'consumes' or 'mayConsume' call.
