Get and set the list of coordinates of the catchment

A overall data interface for cathcment data, containing data properties that are common for all catchments.

This interface contains data and parameters for setting up a catchment model, and represents as such only setup data. Computational variables and methods are not included in this interface. It can be used to explore data and parameters required when setting up the catchment model.

Get and set the central point of the catchment
