DynamicalReflectivityModel: missing parameters

[dkriegner]

The DynamicalReflectivityModel does not use the resolution_width, sample_width, and beam_width parameters which SpecularReflectivity is using.

Does it make sense to add this functionality or do these parameters not make sense here?

My feeling is that since the two models calculate almost the same thing it that the parameters should be added. I guess that resolution_width is in particular easy since its just a convolution of the result where the respective function is already available in Model.convolute_resolution(x, y)

The other two might be more complicated since a consistent handling should be found for transmitivity and reflectivity.

@nlaanait : I would be very much interested in your opinion on this issue.
