I'm trying to create a simple app using the MahApps.Metro `HamburgerMenu` control. So far I've set up my Main Window as described in the examples:

```
<Controls:MetroWindow x:Class="HamburgerDemo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:HamburgerDemo"
        xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Controls:MetroWindow.Resources>
        <DataTemplate x:Key="HamburgerMenuItem" DataType="{x:Type Controls:HamburgerMenuGlyphItem}">
            <Grid Height="48">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="48" />
                    <ColumnDefinition />
                </Grid.ColumnDefinitions>
                <TextBlock Margin="12"
                       HorizontalAlignment="Center"
                       VerticalAlignment="Center"
                       Text="{Binding Glyph}" />
                <TextBlock Grid.Column="1"
                           VerticalAlignment="Center"
                           FontSize="16"
                           Text="{Binding Label}" />
            </Grid>
        </DataTemplate>
    </Controls:MetroWindow.Resources>
    <Grid>
        <Controls:HamburgerMenu ItemTemplate="{StaticResource HamburgerMenuItem}">
            <Controls:HamburgerMenu.ItemsSource>
                <Controls:HamburgerMenuItemCollection>
                    <Controls:HamburgerMenuGlyphItem Glyph="1" Label="Page 1"/>
                    <Controls:HamburgerMenuGlyphItem Glyph="2" Label="Page 2"/>
                </Controls:HamburgerMenuItemCollection>
            </Controls:HamburgerMenu.ItemsSource>
        </Controls:HamburgerMenu>
    </Grid>
</Controls:MetroWindow>

```

I'd like each menu button to link to a specific `Page` which will be loaded into a `Frame` when clicked, however I can't figure out how to do this.

I noticed that the `HamburgerMenuGlyphItem` does have a property `TargetPageType`, and I imagine that this might be the key but I have no idea how to use this.

If there are better methods to loading content using this control or different design patterns I would love to hear them.
