{- Brick's widget:
It is a FocusRing over many list's. Each list contains the information for each tool. Each list has an internal name (for Brick's runtime)
and a label which we can use in rendering. This data-structure helps to reuse Brick.Widget.List and to navegate easily across
Consider this code as private. GenericSectionList should not be used directly as the FocusRing should be align with the Vector containing
the elements, otherwise you'd be focusing on a non-existent widget with unknown result (In theory the code is safe unless you have an empty section list).
- To build a SectionList use the safe constructor sectionList
- To access sections use the lens provider sectionL and the name of the section you'd like to access
- You can modify Brick.Widget.List.GenericList within GenericSectionList via sectionL but do not
modify the vector length
