#SOLID Principles with ruby examples

##SRP - Single responsibility principle A class should have only a single responsibility.

Every class should have a single responsibility, and that responsibility should be entirely encapsulated. All its services should be narrowly aligned with that responsibility, this embrace the high cohesion.

##OCP - Open/closed principle Software entities should be open for extension, but closed for modification.
