Entities can have one of three colors: - red : user input is required within the this entity or it's child entities below, to determine all information needed for this entity
- blue : no more user input is required within this entity; nevertheless some information is not yet determined. A reason can be that information in other entities has to be determined first.
- black : all information within the entity is determined, thus no user input is required and or no parameters need to be calculated.
