Instance-creation methods are class methods that create new instances.
Initializors perform initialization work, such as assigning values to the instance variables of new instances.
If you want to incorporate a variable-initializing initializor into an instance-creation method for a given class, then instantiate the following class-method pattern:
```
new 
  ^ super new initialize 
and then instantiate the following instance-method pattern: 
initialize 
  instance variable := initial value. 
  . 
  . 
  . 
```
