As I said in the initial thread: I didn't just plan to dump the code
here and leave, I am willing to maintain tensor support in the
foreseeable future. (Obviously, I can't promise anything for the distant
future, but that's life.) If it does make into Eigen's unsupported/,
then I will continue working on it and making it more useful for more
generic applications. First goal would probably be to construct
expression templates so that assignments, binary operations (+, -) and
scalar multiplication work. (Which means basically just copying and
adjusting Eigen's current logic for matrices/vectors.)
