Create a layer with the following parameters:

- sublayers: number of sublayers at the upper surface used to calculate roughness
- name: an optional string to use as the name of the layer
Numerical parameters have minimum/maximum values that are going
to be used for fitting. To input just the value, just enter a single number.
To input the value, minimum and maximum, you should enter a
triplet (list,set, numpy array, etc)
