/// If you want to find a Button by it's name and value this example shows you how to use

/// IE ie = new IE("www.yourwebsite.com/yourpage.htm");

/// Button myButton = ie.Button(Find.ByName("buttonname").And(Find.ByValue("Button value")));

/// You can also use the & or && operators, resulting in a bit more readable code.
