/// REVISION HISTORY:\n
///     11 Jun 2012 : P.Jones - Refactor of GLG4PosGen.
///
///  \details  Multiple position points can be added by calling the
///           /generator/pos/set command multiple times e.g:
///           /generator/pos/set 0 0 0
///           /generator/pos/set 1000 0 0
///           For events at the centre and 1m on x axis.
