ndarray and shared pointer

Example of how to access ndarray data in psana module through the shared pointer and construct ndarray<const T,NDim>

Code Block
        shared_ptr< ndarray<T,NDim> > shp = evt.get(m_source, m_key, &m_src);
        if (shp.get()) {

          ndarray<T,NDim>* pnda = shp.get();
          ndarray<const T,NDim> nda_const(pnda->data(), pnda->shape());

          ndarray<const T,NDim> nda_const(shp->data(), shp->shape());
        }
