/*
* More info: https://en.wikipedia.org/wiki/Template_method_pattern
* Usage
* The template method is used in frameworks, where each implements the invariant parts of a domain's architecture, leaving "placeholders" for customization options.
* This is an example of inversion of control. The template method is used for the following reasons:
*
* Let subclasses implement varying behavior (through method overriding).
*
* Avoid duplication in the code: the general workflow structure is implemented once in the abstract class's algorithm,
* and necessary variations are implemented in the subclasses.
*
* Control at what point(s) subclassing is allowed. As opposed to a simple polymorphic override,
* where the base method would be entirely rewritten allowing radical change to the workflow, only the specific details of the workflow are allowed to change.
