- selectedItems may have the whole geometry, parts (collection elements),
or linestrings, or a mix of all three. But there will be no duplicate data
(that is, you can't select both the whole and one of its parts -- only the
whole geometry will be selected; similarly, you can't select a part and
one of its linestrings -- only the part will be selected).
geometryWithSelectedItems - a clone of the geometry containing the selected items.
Because geometryWithSelectedItems is a clone, feel free to modify it, as no other
parties reference it. Then return it (or return something totally different).
selectedItems - clones of the selected items (each of which have class Geometry).
selectedItems' elements are "live"; that is, they are objects taken from geometryWithSelectedItems.
So, for example, modifying selectedItem's coordinates will modify geometryWithSelectedItems'
- a new Geometry for the Feature (typically geometryWithSelectedItems, but can
be a completely different Geometry), or an empty geometry to (undoably) remove the Feature from the Layer
