Behavioural Design Pattern: Template Pattern

Template Pattern defines the skeleton of a function in an operation, delegating some steps to its subclasses. It is an extremely prevalent method for retaining code. This is merely its primary advantage.

When common behavior among subclasses should be consolidated into a single common class to prevent duplication, this method is implemented.
