title: Disable globally ripple effect angular 2 app
body: <p>I have an app which is using material 2, i would like to globally disable the ripple effect for all components or directives that use it. I don't want to do this overriding css classes. One thing that comes in my mind is creating a directive which can extend MdRipple and then override its properties, not sure tho. I would like to know your opinion or example how this can be done in the right way.</p>
