Detailed Description

Interface for vectors in Diana analysis.

Author: R. Faccini, M. Vignati

This class is intended for use as mathematical vectors, not as container vector (like std::vector). Every class written within the DIANA framework should use this class instead of C arrays or std::vector<double>

Examples: GlobalDataManagerExample.C, MTutorialAveragePulse.cc, MTutorialPulseShape.cc, and ScanEvents.C.
