Subject:  * coefficient wise operators are more generic, with controllable
 result type.    - compatible with current STL's functors as well as with the
 extention proposal (TR1)  * thanks to the above, Cast and ScalarMultiple have
 been removed  * benchmark_suite is more flexible (compiler and matrix size)
