Detailed Description

Tree model with maps available by configured providers (see Settings::GetMapProviders).

Every map provider have to expose list of maps by json. Json format example:

[
 {
   "version" : 10,
   "timestamp" : 1480801927,
   "name" : "Czech Republic",
   "directory" : "europe/czech-republic-10-20161203",
   "size" : 622036876,
   "map" : "europe/czech-republic"
 },
 {
   "dir" : "europe",
   "name" : "Europe"
 }
]
