Remove helloworldbundle page

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As this information is wildly out of date and doesn't seem to be supported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.

-This document aims to describe how to create an application bundle for
-Apertis using the SDK image.
-
-## Creating a bundle from Eclipse
-
-### Prerequisite
-
-  - Apertis 16.03 SDK image, download from
-    [here](https://images.apertis.org/daily/16.03/images/sdk/)
-  - and set up in [VirtualBox]( {{< ref "/virtualbox.md" >}} )
-
-**Note**: This documentation was tested against the 16.03 i386 images.
-
-### Set up for using the Simulator
-
-For the reason of license, Simulator is temporally removed on Apertis
-16.03. It should be installed by manual from Apertis 15.12
-
-### Run Eclipse
-
-Open Eclipse. You will need to select a workspace if you have not run it
-before. On Apertis 16.03, several Eclipse plugins are missing so they
-should be installed by //Help// -\> //Install New Software//.
-
-#### Install JET Plugin
-
-Add update manager URLs listed below.
-
-1.  Juno - <http://download.eclipse.org/releases/juno>
-2.  EMF - <http://download.eclipse.org/modeling/emf/updates/releases/>
-3.  M2T - <http://download.eclipse.org/modeling/m2t/updates/releases/>
-
-Then, install *M2T JET SDK 1.1.1* -\> *Java Emitter Templates (JET)*
-
-#### Install Autotools Plugin
-
-If Eclipse Mars repository URL is not registered in update manager,
-please add it first.
-
-1.  Eclipse Juno repository -
-    <http://download.eclipse.org/releases/juno>
-
-Then, install *C/C++ Autotools Support*.
-
-Now Eclipse is ready to create a project, select the *Mildenhall
-Project* button in the middle of header menu of Eclipse to start the
-project creation wizard.
-
-![<File:0001> eclipse mildenhall
-project.png](/images/0001_eclipse_mildenhall_project.png)
-
-### Use the project wizard
-
-1.  Select *Create new project*, then press the *Next* button.
-2.  Enter an *Application Name* into the wizard
-3.  Enter an *Bundle ID* (less than 64 characters including Application
-    Name), then press the *Next* button.
-4.  The *Application Type Selection* wizard window will open. Press the
-    *Configure* button.
-    You can add the other types of application here using the *Add*
-    button. The supported types are;
-      - APPLICATION
-      - SERVICE
-      - AGENT-SERVICE
-      - EXT-APPLICATION
-    However, only the *APPLICATION* type is supported at this time. For
-    more details, please refer to
-    [HelloWorldBundle\#Limitations]( {{< ref "/helloworldbundle.md#limitations" >}} ).
-    ![none|320px|](/images/0004_application_type_selection_with_box.png)
-5.  The details of the bundle configuration can be modified on
-    *APPLICATION: Manifest Configuration Wizard* window. Press *Next* to
-    continue once you have finished configuring the application.
-    ![none|320px|](/images/0005_application_type_configuration.png)
-6.  Configure the resources on the *Resource Configuration Page*, then
-    press the *Finish* button.
-    ![none|320px](/images/0006_resource_configuration.png)
-7.  You will now return to the *Application Type Selection* window,
-    press *Finish* to complete the application setup.
-
-### Installing a bundle
-
-Once the bundle creation is completed in the wizard, Eclipse will start
-compiling it automatically.
-
-Open a terminal to finish the remaining steps to install the bundle for
-running in the Simulator after changing to application source code
-directory:
-
-    $ cd path/workspace/HelloWorld
-    $ make
-    $ sudo make install
-    $ sudo make install-app2simu
-
-## Running a bundle
-
-Now, the bundle is ready to run with the Apertis Simulator. We have
-several options for running the Apertis Simulator:
-
-  - Command line:
-        $ Start_Simulator.sh
-  - Eclipse Icon:
-    ![none|240px](/images/simulator_button.png)
-
-If the deployment process is done successfully, *HELLOWORLD* menu is
-shown in simulator screen.

-
-## Limitations
-
-The current Mildenhall plugin for Eclipse has some limitations that you
-should be aware of:
-
-  - It does not support creating a project from the *Project Explorer*
-    context menu (*Project Explorer* \> right button click \> *New* \>
-    *Project* menu).
-  - You can edit the configuration of an existing project only through
-    the wizard. The Project menu does not support Mildenhall projects at
-    this time.
-  - Default application type is selected as *APPLICATION*, and it can
-    not be removed. In addition, if the other type is added,
-    *autogen.sh* fails:
-        configure.ac:129: error: `resources/views/view1/Makefile' is already registered with AC_CONFIG_FILES.
-        ../../lib/autoconf/status.m4:288: AC_CONFIG_FILES is expanded from...
-        configure.ac:129: the top level
-  - Do not modify *Menu Entry* \> *Menu Title* on *Application: Manifest
-    configuration wizard*. Due to a character encoding problem, it will
-    not be recognized by the Simulator if it is changed.
-  - Due to SDK permission policy, *make install* and *make
-    install-app2simu* are not supported in the Eclipse environment. They
-    should be run from a terminal as root (for example, using the *sudo*
-    command).
-    **Alternative**: To use the macro in the Eclipse environment, we can
-    change permissions of the target directory, */Applications*:
-        sudo chown user -R /Applications
-    Then, the bundle can be installed by running the Eclipse macro,
-    *Make Targets* \> *Build* \> *install-app2simu*
-    **Note**: it is not recommended because Apertis is designed for
-    multi-user environment. Although this works for a specific bundle,
-    it can cause other problems.

 The running environment of an application bundle changes as Apertis is
 developed. The instructions for writing an application bundle on the SDK
 have been checked and updated at

+[HelloWorldBundle](). The process of walking
 through these steps to create an example application revealed some bugs
 in the SDK, which have been fixed.
