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