* \brief This functor performs a linear transform of its input.
*
* \f[ output = a*input + b \f]
*
* Coefficient a is a scalar, its type is templated (default is double).
* Coefficient b has the same type as output type. Standard casting is applied
* between input and output type.
*
* TInput and TOutput type are supposed to be scalar types.
