title: Load Curve from file instead using Content Manager
body: <p>I'm looking to load a Curve file in XNA but not through the content manager process e.g. Load("").</p>
  
  <p>Is there any way to do this?</p>
  
  <p>For example:</p>
  
  <p>Curve curve = new Curve("filename"); or
  Curve curve = Curve.FromFile("filename"); // similar to loading texture2d and song.</p>
