title: Using Watir-webdriver how to check the URL of a page
body: <p>I am new to watir-webdriver automation, apologies if its a basic question of automation. But the thing is I am automating pagination of a website where the URL of the website changes as the user changes the page 
  say the URL is www.example.co.uk/news which has pagination when the user clicks next button on the pagination the URL changes to www.example.co.uk/news?page=1 </p>
  
  <p>I want to check the URL at this point to see if the URL is correct.
  But I can't really find a way to get the URL of the current page.</p>
