A generic block simply runs a predefined algorithm which can be passed to the constructor of the block. Such an algorithm could theoretically calculate any output from a given set of inputs. It can be especially valuable for cases like the following. A signal value must be applied with an offset and a scale. How to achieve this?

1. Use a constant block delivering the offset together with a sum block which adds the offset to the signal. Finally, a gain block applies the desired scale. All in all, you will use three different blocks.
2. Use a generic block and define the necessary algorithm as follows

   GenericBlock<> gen([&]() {
     gen.getOut(0).getSignal().setValue(gen.getIn(0).getSignal().getValue() + 0.1) * 1.1);
     gen.getOut(0).getSignal().setTimestamp(gen.getIn(0).getSignal().getTimestamp());
   })

Such a generic block can save valuable execution time in reducing the number of necessary blocks. It can also be useful when a given algorithm cannot be stitched together from predefined blocks.
