/**
 * @file pylith/utils/arrayfwd.hh
 *
 * @brief Forward declarations for PyLith array objects.
 *
 * These are generally just forward declarations for C++ STL objects.
 *
 * For simple types (i.e., int and double) std::valarray provides some
 * features that std::vector does not have, such as operating on the
 * whole array at once.
