/**
* Complex hierarchies
*
* A hierarchical schematic uses sheets (hierarchical sheets) included in a given sheet.
* Each sheet corresponds to a schematic drawing handled by a SCH_SCREEN structure. A
* SCH_SCREEN structure contains drawings, and have a filename to write it's data. Also a
* SCH_SCREEN displays a sheet number and the name of the sheet.
*
* In simple (and flat) hierarchies a sheet is linked to a SCH_SCREEN, and a SCH_SCREEN is
* used by the single hierarchical sheet.
*
* In complex hierarchies the same SCH_SCREEN (and its data) is shared by more than one sheet.
* Therefore subsheets (like subsheets in a SCH_SCREEN shared by many sheets) can also be
* shared. So the same SCH_SCREEN must handle different symbol references and unit selections
* depending on which sheet is currently selected, and how a given subsheet is selected. Two
* sheets share the same SCH_SCREEN (the same drawings) if they have the same filename.
*
* In KiCad each symbol and sheet receives (when created) a uuid. So each sheet has 2 id: its
* uuid (which cannot change) and its name (that can be edited and therefore is not reliable
* for strong identification).
* A given sheet in a hierarchy is fully labeled by its path (or sheet path) that is the list
* of uuids found to access it through the hierarchy. The root sheet is /. All other sheets
* have a path like /1234ABCD or /4567FEDC/AA2233DD/. This path can be displayed as human
* readable sheet name like: / or /sheet1/include_sheet/ or /sheet2/include_sheet/
*
* So to know for a given SCH_SCREEN (a given schematic drawings) we must:
* 1) Handle all references possibilities.
* 2) When acceded by a given selected sheet, display (update) the
* corresponding references and sheet path
*
* The class SCH_SHEET_PATH handles paths used to access a sheet. The class SCH_SHEET_LIST
* allows one to handle the full (or partial) list of sheets and their paths in a complex
* hierarchy. The class EDA_ScreenList allows one to handle the list of SCH_SCREEN. It is
* useful to clear or save data, but is not suitable to handle the full complex hierarchy
* possibilities (usable in flat and simple hierarchies).
