/// 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:CloseableTabItemDemo"

/// 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:CloseableTabItemDemo;assembly=CloseableTabItemDemo"
///
/// 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
