wiki page for Structural Systems and Multiples structures, tbc

[david69]

in the current 0.20, we have under Arch/Structure tools, 3 shortcuts:
- Structure and its wiki page Arch_Structure
- Structural Systems, no page
- Multiples structures, no page

do they deserve a wiki page?
or, where are they documented?

the theory is that each freecad command has a separate wiki page, so they can be opened with the "what's this" button. indeed these tools are new, they need a new wiki page
