We could also provide some functionality to convert from a cube representation of an image to a flattened matrix.  It's a lot easier in the internal code to support only one type of object, especially because in this case the slices and columns would have to be handled differently.

I suppose we could add something like `data::FlattenCube(const arma::Cube<eT>& cube, arma::mat& matrix);`, but honestly I'm not sure that many people are loading their images as cubes (does Armadillo have built-in support for that?  I know `data::Load()` won't do it).
