 Actually the implementation of the '''size''' free function has two weak
 points:
 1. It does not make use of the new uBLAS traits system introduced by
 Gunter.[[BR]]
   E.g.: ''typename ExprT::size_type'' should become ''typename
 matrix_traits<ExprT>::size_type''

 2. It does not fully support expression types. The current support is
 error prone and not user-friendly.[[BR]]
   E.g.: if ''ExprT'' is an expression type and ''e'' is a variable of type
 ''ExprT'', then one has to call ''size(e())'' instead of simply
 ''size(e)''.

 I suggest to change the '''size''' operation in order to fix the above
 issues.
