Contract for ECF identity
ECF IDs are immutable once constructed, and unique within the containing Namespace.
ID instances are created via the Namespace.createInstance(...) method. This method is called by the IDFactory.createID(...) methods for the given Namespace. So, for example, to create an ID instance with the name "slewis":
```
 ID id = IDFactory.getDefault().createID(namespace, "slewis");
 
```

- Method Detail
  - equals
```
boolean equals(Object obj)
```
    Specified by:
    
    equals in interface Principal
    
    Overrides:
    
    equals in class Object
  - hashCode
```
int hashCode()
```
    Specified by:
    
    hashCode in interface Principal
    
    Overrides:
    
    hashCode in class Object
  - getName
```
String getName()
```
    Get the unique name of this identity.
    
    Specified by:
    
    getName in interface Principal
    
    Returns:
    
    String unique name for this identity. Will not be null, and must be a unique String within the Namespace returned by getNamespace()
  - getNamespace
```
Namespace getNamespace()
```
    Get the Namespace instance associated with this identity
    
    Returns:
    
    Namespace the Namespace corresponding to this identity. Will not return null.
  - toExternalForm
```
String toExternalForm()
```
    Get this ID instance in String form. Will not return null.
    
    Returns:
    
    String that is external representation of this ID
