This file defines a number of containers. Some are just typedefs of
std:: containers, while others are wrappers around
std:: containers introduced in the hope of reducing the
amount of debugging and code duplication.
Do not make changes in this file. If you need to modify any of the standard containers used in Pythia7, edit a copy of this file and include it in an alternative config file which can be included in the main Pythia7.h config file using the macro PYTHIA7_ALTERNATE_CONFIG.
