Request for adding TMultiView examples

[GalbertReloaded]

The demo projects for the TFrameStand component could be widened by adding some examples about TMultiView. In particular, I would be very interested in an implementation that may include a TTreeView item for showing a nested menu layout, possibly by a sliding animation effect as in the following example:

Main screen (still without content)

After clicking on the "Play" button", content slides to the right

The menu supports a nested organization
