New layout

[timbrownls20]

I notice there is SimpleLayoutComponent. Could we create an alternative component with a different layout. We are interested in changing the left hand side to show content, layout and custom rather than the block tree.

I've created a mock up[ to demonstrate our idea.

SimpleLayout is just a simple Layout example, you can easily change it.
