Is a map snychronized with any or a specific map?
Invoking this method sets a Shiny input that returns TRUE when
the map is synchronized with another map. If syncwith is
set, TRUE is returned if the map is synchronized exactly
with that other map.
Details
The Siny input name is combined of the map-id and "_synced".
For a map with id map1 the input can be retrieved with
input$map1_synced.
