 Module containing the functions to handle the Moe&Distrefano data
 
 This class object is an extension to the population grid object

+TODO: The values from M&S are from bincenters, but our method makes it that the bincenter value is used as an edge value. So e.g. taking an eccentricity of 0.04 wll give 0 because its lower than the 0.05 (minimum) point. But it should probably give a value, even if we choose eccentricity = 0
