> Since all data message types at the moment are 1-dimensional, a "tensor" message will contain an array of dimensions and an order flag (C order vs. Fortran order) to enable data to be interpreted as multiple dimensions. This is similar to multidimensional arrays in APL or Fortran or MATLAB, ndarrays in NumPy, etc.
