        New-BTButton -Snooze -Content 'Sleep' -Id 'TimeSelection'

        This command creates a button which will snooze the Toast for the time selected in the SelectionBox with the ID 'TimeSelection'. The button will show the text 'Sleep' rather than 'Dismiss.'

        This command creates a button with the display text "Blog", which will launch a browser window to "http://king.geek.nz" when clicked.

        .EXAMPLE
        $Picture = 'C:\temp\example.png'
        New-BTButton -Content 'View Picture' -Arguments $Picture -ImageUri $Picture

        This example creates a button with the display text "View Picture" with a picture to the left, which will launch the default picture viewer application and load the picture when clicked.
