`UseCompositionInsteadOfInheritance(config: Config = Config.empty)`

A rule suggesting the use of composition instead of inheritance. It will help you test for Liskov Substitution.

The rule will fire every time inheritance is introduced, unless you derive from a class that exists in a third party package.
This will reduce the amount of warnings created where the framework or library are forcing you to introduce inheritance.

Remember to configure this rule correctly by adding:
"yourUniquePackageName" : "io.github.mkohm"
replacing "io.github.com" with your unique package name.
