/** Linear layer for #GradientMachine#.
Formally speaking, $ouputs[i] = \sum_j w_{ij} inputs[i] + b_i$.\\
$w_{ij}$ and $b_j$ are in #params#, with the following structure:\\
$w_00... w_0n, b_0, w_10... w_1n, b_1, ...$\\
If you want, you can add a weight decay which looks like
$\sum_i,j w_{ij}^2 + sum_i b_i^2$.
Options:
\begin{tabular}{lcll}
"weight decay" & real & the weight decay & [0]
\end{tabular}
