{- 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
