title: Highlight entire row when cell is active
body: <p>How to design a sheet script that would result in an active row being highlighted? </p>
  
  <p>I would like to have an entire row change color of font or background when one cell in that row is active.</p>
  
  <p>I don't want the trigger to be any specific value in the cell, just clicking on a cell should trigger the highlight for the whole row that cell belongs to.</p>
