// $common\cvec.hpp 1.5 milbo$ cvec is like STL vector but checks for out of range indices when _DEBUG is defined.
// Warning: this is raw research code -- expect it to be quite messy.
//
// If _DEBUG is not defined the MSC compiler generates code with the same efficiency as vector.
// I checked this by looking at disassembled code.
// Lifted from Ulrich Breymann "Designing Components with the C++ STL" section 9.1
