This page describes a workflow utilising a simulator in the SDK to allow
the HMI to be run as if on a device for development. Based on the
description provided, it seems that the simulator was removed from the
16.03 release due to licensing issues. Additionally the description
describes a "Mildenhall plugin for Eclipse", which I suspect was a part of
the "apertis-eclipse-plugins", which haven't been available since before
v2019.

As this information is wildly out of date and doesn't seem to be supported
any longer, delete it as it's miss-leading.
