.NET Basic LTI XML file loader

[Steve Lewnau]

Here's a .NET class to load a Basic LTI xml file. It definitely works
with the sample file "Example_CC1b.xml", but may need more properties.

---------------------------
Loading XML file example:

string XMLFileName = @"C:\blti.xml";
System.IO.StreamReader sr = new StreamReader(XMLFileName);
XmlSerializer xs = new XmlSerializer(typeof(Blti));
Blti blti = (Blti)xs.Deserialize(sr);

public class Blti
