<!--
This scenario demonstrates a simple task as the evaluation of GPD model in a single kinematic point for specific GPD types only.

The result of this function is printed out to the standard output.
These are the values for all defined in the model GPDs, including singlet and non-singlet combinations for quarks.

Note that you can use this example to select specific GPD types in the evaluation of CFFs and observables.
