/**@class LocationDialog
*Dialog for changing the geographic location of the observer. The
*dialog is divided into two sections.
*
*The top section allows the location to be selected from a database
*of 2000 cities. It contains a MapCanvas (showing map of the globe
*with cities overlaid, with a handler for mouse clicks), a TQListBox
*containing the names of cities in the database, and three KLineEdit
*widgets, which allow the user to filter the List by the name of the
*City, Province, and Country. In addition, the List
*can be filtered by location, by clicking anywhere in the MapCanvas.
*Doing so will display cities within 2 degrees of the clicked position.
*
*The bottom section allows the location to be specified manually.
*The Longitude, Latitude, City name, Province/State name, and Country name
*are entered into KLineEdits. There is also a TQPushButton for adding the
*location to the custom Cities database. If the user selects "Add" without
*filling in all of the manual entry fields, an error message is displayed.
