[ublas] Expression/Container differentiation

Dear All,

I have committed and experimental branch to experiment with a better way to 
differentiate between Expressions and Containers.

Branch is uBLAS_assignment_sematics (note the typo of 'semantics')

I introduces new base classes vector/matrix_container. All Containers are now 
derived from these classes. Containers can now be differentiated from general 
Expressions by their base type.

Vector Matrix Expression no longer are default constructable.

A new header 'expression_types.hpp' brings all this together.

So far I have implemented a few '+=' specialisations for containers which 
avoid the temporaries in these assignments.
