title: Wrapping <mat-card> within a container - angular/material
body: <p>Is it possible to:</p>
  
  <ol>
  <li>Display  components of defined width in a row rather than the default column</li>
  <li>Wrap the cards within another defined container</li>
  </ol>
  
  <p>I have tried to do this without success so far....</p>
  
  <p>material buttons DO wrap in this way, I am just wanting to replicate the experience with cards...</p>
