body: <p>Angular is it possible to detect if query Paramter has changed? 
  I have a Component that handles 2 query paramters and according to what paramter you come with it sets some variables true or false. The Problem is if im on my component with queryparameter 1 the qp can change to the second paramter without leaving the component and in that case i need to set variables diffrently. So how do I detect that? Is that even possible?</p>
