Detailed Description

Class to store data from CAEN V1190. We store the information as a vector of TDCMeasurement's Question: do we need a way of retrieving information about TDCs that have no measurements? Currently this information is not exposed. For the definition of obscure variables see the CAEN V1190 manual.
