max@0: //! Class for storing data required for delayed binary operations,
max@0: //! such as the operands (e.g. two matrices) and the binary operator (e.g. addition).
max@0: //! The operands are stored as references (which can be optimised away),
max@0: //! while the operator is "stored" through the template definition (glue_type).
max@0: //! The operands can be 'Mat', 'Row', 'Col', 'Op', and 'Glue'.
max@0: //! Note that as 'Glue' can be one of the operands, more than two matrices can be stored.
max@0: //!
max@0: //! For example, we could have: Glue<Mat, Mat, glue_times>
max@0: //! 
max@0: //! Another example is: Glue< Op<Mat, op_htrans>, Op<Mat, op_inv>, glue_times >
