[platform-ui-dev] Component framework demo

[Stefan Xenos <Stefan_Xenos@xxxxxxxxxx>]

For those of you interested in the API
for nesting views and editors, I've attached a demo of the component framework
to bug 46207.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=46207

This is a big change and I want to gather
some community input before it goes in. If you're planning to review the
patch (or parts thereof), please e-mail me so that I know who to expect
feedback from.
