2c00ac0b53 Implement generic scalar*expr and expr*scalar operator based on scalar_product_traits.
This is especially useful for custom scalar types, e.g., to enable float*expr<multi_prec> without conversion.

811aadbe00 Add syntactic sugar to Eigen tensors to allow more natural syntax.
Specifically, this enables expressions involving:

scalar + tensor
scalar * tensor
scalar / tensor
scalar - tensor
