nwLat - NorthWest latitude of area of interest.

nwLon - NorthWest longitude of area of interest.

seLat - SouthEast latitude of area of interest.

seLon - SouthEast longitude of area of interest.

graphicList - Vector to add Locations to. If null, the LocationHandler should create a new Vector to place graphics into.

Returns:

Either the OMGraphicList passed in, or the new one that was created if null.
