 * The MapData represents all the data needed to draw a map. MapMetaData is
 * something like streets etc. that do not have any special locatable location.
 *
 * Since in the database might be the data of a whole city, this data object
 * only has some part of the available data and needs to reload, which we call
 * here "moving the window".
 * The window in this case is the area of the data which we want to have
 * available. This should always be quite greater than whats displayed, since
 * we dont want to constantly reload data from database.
 * We "forget" the data thats not needed any more if the total amount of data
 * exceeds a certain limit.

/*
 * Notes:
 *
 * - Need a list with all wlan locations (for wlan information)
 * - Need a list with all "normal" locations (without wlan information)
 * - Need a list with all the other "nice" meta data like streets etc.
 * - all the locations should have some connection to those in the wlan locator
 *   so we can smoothly display them on the map. Should we do this by the dbid
 *   ? perhaps, it should be a unique identifier...
