// If you want to create a new object that you can read and write, use this constructor:
//
//   l1t::PrescalesVetosFractHelper x(new L1TPrescalesVetosFract());
//
// If you wish to read the table from the EventSetup, and will only read, use this:
//
//   const PrescalesVetosFractHelper * x = PrescalesVetoFractsHelper::readFromEventSetup(...)
//   //...
//   delete x;
//
// If you wish to read the table from the EventSetup, but then be able to edit the values locally, use this:
//
//   PrescalesVetosFractHelper * x = PrescalesVetosFractHelper::readAndWriteFromEventSetup(...)
//   //...
//
// but there's a performance penalty as a copy is made.
 
//
// This class does not take over responsibility for deleting the pointers it is
// initialized with.  That is responsibility of the calling code.
