fix #10391: Add support for "not element of" operator

  • implement 4 new operators: ⊆,⊈,⊇,⊉
  • ⊆ is a synonym for the existing ∈ operator that uses the ContainsFinder, it

matches for elements which contain one or more elements matching the left Selectors

  • ⊈ matches for elements which do not contain any element matching the left Selectors (also uses the ContainsFinder)
  • ⊇ matches for elements which are contained in an element matching the left Selectors, it uses the InsideOrEqualFinder and is typically slower than ⊆, so it is probably only usefull for the search dialog
  • ⊉ matches for elements which are NOT contained in any element matching the left Selector
  • Both ContainsFinder and InsideOrEqualFinder work with areas, an area is either descibed by a closed way or a valid, complete relation of type=multipolygon or type=boundary. Incomplete objects do not contain something, invalid objects produce unpredictable results.
  • An element A contains another element B when it is an area and when B is either a Node inside the area of A, or when it is also an area that is fully inside or equal to A. An element is not inside a relation when it is a member of that relation.
  • hint: with ∈,⊆,⊈ prefer to use area selector instead of * for the right side, for ⊇,⊉ use area selector on the left side
