title: Cannot set individual icon heading using SharpKML
body: <p>Using SharpKML library from VB (VS2010), I can create kml files with a custom icon for each placemark.  The placemarks are created in a loop and I want to set the icon's heading property for each placemark.</p>
  
  <pre><code>'Define the style for the icon
  Dim kmlStyle As New SharpKml.Dom.Style
  kmlStyle.Id = "ShipIcon"
  kmlStyle.Icon = New SharpKml.Dom.IconStyle
  kmlStyle.Icon.Icon = New SharpKml.Dom.IconStyle.IconLink(New System.Uri("http://www.mysite.com/mapfiles/ship4.png")) 
  kmlStyle.Icon.Scale = 1
  
  Poscommand.CommandText = "SELECT * FROM Ships"
  PosReader = Poscommand.ExecuteReader()
  
  While PosReader.Read()
     'Add placemark for position
     kmlPosPoint = New SharpKml.Dom.Point
     kmlPosPoint.Coordinate = New SharpKml.Base.Vector(PosReader("Lat"), PosReader("Lon"))
     kmlPosPlaceMark = New SharpKml.Dom.Placemark
     kmlPosPlaceMark.Geometry = kmlPosPoint
     kmlPosPlaceMark.Name = "My Name"
     kmlPosPlaceMark.StyleUrl = New System.Uri("#ShipIcon", UriKind.Relative)
     'SET icon.heading HERE???  How to access icon heading property for this placemark only???
  End While
  </code></pre>
  
  <p>Can anybody help me set the icon heading for an individual placemark using SharpKML?</p>
