title: Specify my own select dropdown for page size
body: <p>I would like to have a select menu that is outside of the datatables grid that I can use to control the page size.</p>
  
  <p>I am aware that I can move the page size dropdown anywhere within the grid using the <code>dom</code> option and setting <code>&gt;l</code>. However, I want to use a dropdown that is outside of the grid, so I cannot use this option.</p>
  
  <p>I am assuming I either have to handle the change event on my own dropdown, then do something to set the page size property and then call <code>.draw()</code>.</p>
  
  <p>Or even better, when initializing the datatable, tell it which select dropdown to use for page size and have it handle the change.</p>
