Navigation Bar creation

In order to improve the navigation in the application, we will add a navigation bar which will show at any time user position into the application and allows to navigate quicker.

The presentation

It will be shown like this : Concern > Feature | Goal > Model > View

When the user tap on an arrow, il will show the navigation menu
One navigation menu must be visible at the same time
When labels doesn't fit the menu, there is "..." at the end.
An icon inside each navigation bar part, indicate part type

Menus shows :

Under the Feature part : other features related to the concern and their models, and goals of the concern.
Under the Model part : other models
Under the view part : the other views. operation list for message and state views. The current part is not shown in menus.

The navigation

One tap on parts (icon or label) of the navigation bar allows to navigate
Double tap on parts (label) of the navigation bar renames the part (only on feature and models)
One tap on sub list item in menu goes to the related scene/view
One tap on "header" in menu of the view parts, shows all the items on the same view.

Missing features

integrate the navigation to TouchCORE.
give a maximum width to the menu in order to minimise it size on the screen. text inside must fit to the width. For example, add "..." at the end of long texts, or decrease space between letters. This work must be done into the RamTextComponent when a maximum size is given.
At the integration, remove the section eObject from its menu.
Add management of scene history, in order to use correctly the back button and pop all the sections between the previous state and the new one.
Add action to the header of a section, in order to change scene when it's clicked.
