Customising HamburgerMenu

[NZSmartie]

The HamburgerMenu is designed for Windows Metro theme. But lacks the ability to customise (i guess themes it up) for MaterialDesign.

For example, MaterialDesign's Navigation Drawer uses a separate colour for the hamburger menu button and the menu items

Looking at

MahApps.Metro/src/MahApps.Metro/Themes/HamburgerMenuTemplate.xaml

Lines 395 to 408 in 17c935c

	<Button x:Name="HamburgerButton"
	Width="{TemplateBinding HamburgerWidth}"
	Height="{TemplateBinding HamburgerHeight}"
	Margin="0 0 0 8"
	Padding="{TemplateBinding HamburgerMargin}"
	HorizontalAlignment="Left"
	VerticalAlignment="Top"
	AutomationProperties.Name="Main button"
	ContentTemplate="{TemplateBinding HamburgerMenuTemplate}"
	Foreground="{TemplateBinding PaneForeground}"
	IsTabStop="{TemplateBinding IsTabStop}"
	Style="{StaticResource HamburgerButtonStyle}"
	TabIndex="0"
	Visibility="{TemplateBinding HamburgerVisibility}" />

the Style is staticly linked and does not allow for customising in an application.

Ideally, i would like to override or derive HamburgerButtonStyle to assign a custom background colour (to match the toolbar).

Could also use this as an opportunity for the other staticly linked resources in the HamBurgerMenu as well for further customisations.
