// DESCRIPTION:
// Base class for a dynamic array. Allows adding, removing, index of,
// and finding of entries with specified value. NOTE: indices in container
// are 1 based, not 0. This means that loops must check from 1 up to and including
// NumObjects() (ei. for( i = 1; i <= list.NumObjects(); i++ ) ).
//
// FIXME: Someday make this 0 based and update all code to match.
//
// WARNING: This file is shared between game, cgame and possibly the user interface.
// It is instanced in each one of these directories because of the way that SourceSafe works.
