https://en.wikipedia.org/wiki/Single_responsibility_principle The #single_responsibility_principle is a computer programming principle that states that every #module or #class should have responsibility over a single part of the functionality provided by the software, and that responsibility should be entirely encapsulated by the class. All its services should be narrowly aligned with that responsibility. Robert C. Martin expresses the principle as, "A class should have only one reason to change."
