title: The default value of timeouts on selenium webdriver
body: <p>I am interested in the default value of timeouts on selenium <code>webdriver.
  ImplicitlyWait</code>, <code>SetPageLoadTimeout</code> and <code>SetScriptTimeout</code>.
  Because I want to know, Do I need to set a values for those timeouts? or the default value is good for selenium webdriver working.
  But I cannot find a correct answer, someone say the default value is 0, and other one say it is 30 sec.</p>
