Detailed Description

template<class Traits>
class EcalTDigitizer< Traits >

Turns hits into digis.

Assumes that there's an ElectroncsSim class with the interface analogToDigital(const CaloSamples &, Digi &);

these are the types that need to be defined in the Traits class.

The ElectronicsSim needs to have an interface that you'll see in the run() method
