The reason why there is no "just load it" function in Octave for this
kind of data is that there is no built-in datatype for matrices with
named (and possibly heterogeneous) columns. Octave's arrays are, in
general, multidimensional and homogeneous (except cell and struct
arrays), and carry no row or column labels.
