and long double.
-define scalar-multiple operators only for the current Scalar type;
 thanks to Gael for expaining how to make the compiler understand
 when automatic casting is needed.
-take ScalarMultiple take only 1 template param, again.
 We lose some flexibility especially when dealing with complex numbers,
 but we gain a lot of extensibility to new scalar types.
