	/// Step 1a) Using this custom control in a XAML file that exists in the current project.
	/// Add this XmlNamespace attribute to the root element of the markup file where it is 
	/// to be used:
	///
	///     xmlns:MyNamespace="clr-namespace:CommonUtils"
	///
	///
	/// Step 1b) Using this custom control in a XAML file that exists in a different project.
	/// Add this XmlNamespace attribute to the root element of the markup file where it is 
	/// to be used:
	///
	///     xmlns:MyNamespace="clr-namespace:CommonUtils;assembly=CommonUtils"
	///
	/// You will also need to add a project reference from the project where the XAML file lives
	/// to this project and Rebuild to avoid compilation errors:
	///
	///     Right click on the target project in the Solution Explorer and
	///     "Add Reference"->"Projects"->[Browse to and select this project]
	///
	///
	/// Step 2)
	/// Go ahead and use your control in the XAML file.
