title: Importing csv/xls format files with smartGWT
body: <p>I am using <code>smartgwt</code> free version (not EE). Is there a built in widget to handle importing <code>.csv</code> or <code>excel</code> format files? 
  I can currently export records from a <code>listGrid</code> to <code>csv</code>. I want to be able to open up another browser, and import the <code>csv</code> file, and based on the configuration that I have exported onto the <code>csv</code> file, re-create the records that I have exported. </p>
