Improved API and logic for mode tree build up
Dedicated interfaces to expose mode tree functionality
- ModeTreeChildIF for objects which can be mode tree children
- HasModeTreeChildrenIF for parent objects
- ModeTreeConnectionIF for connecting parent and child
The EIVE SW was developed with the V-model, which means that lower level components like assemblies, device handlers and controllers are developed first. The previous implementation meant that objects::NO_OBJECT was passed as the parent parameter everywhere. The parent is now not passed to base classes like SubsystemBase and ControllerBase anymore, and there is a deciated function connectModeTreeParent exposed by the ModeTreeConnectionIF to connect a parent component to a mode tree child.
The new connector function does everything in one place: Registering the child in the parent, and setting the parent command queue in the children. This means there is no confusion about the call direction anymore: This function does both.
DHB is now a regular mode tree object, no need for the ChildHandler just to attach it to a subsystem. In my opinion, not every satellite has or needs an assembly for every device handler
