ConsoleScanable

All Known Implementing Classes:

Date, Track
```
public interface ConsoleScanable
```
This interface encapsulates the concept of scanning and editing an implementing class on the console (with a text-based user interface).
Implementing classes provide a method scan that guides the user through the process of reviewing and possibly changing current values. The resulting object is in a consistent state, i.e. it is taken care that no illegal values or combination of values are accepted.

- Method Detail
  - scan
```
boolean scan()
```
    Guides the user through a process that allows scanning/modifying an object with a text-based user interface. Implementing classes may choose to provide a cancel mechanism and/or a keep-old-value mechanism. The user interaction is completely left to implementing classes and must be documented there.
    Documentation should include:
    
    which fields and in which order they can be modified
    
    if and how cancellation and keeping old values works
    
    how illegal inputs are dealt with (message, repeated input of single field or all fields,...)
    Returns:
    
    whether this object was altered or not
