Static icons are icons that can be added or removed from the map, and are typically temporary locations of for example a customers address where work needs to be carried out. The icon could be changed to reflect the current stage of the work (provisioned, in progress, overdue, completed etc).
Notes:
1) Add & Delete messages are arrays, so that icons can be added and removed in bulk.
2) If an icon already exists, the original is removed and replaced with new icon/location.
3) "id" is a unique string, and is also the name of the icon that is displayed below it.
{ "addIcon" : [ { "id":"idRefString", "lat":1.12345, "lon":50.12345, "icon":"buiding.png", "text":"Nice place for fish & chips", } ] }
{ "delIcon" : [ { "id":"idRefString", } ] }
