OpenLayers.Util.getFormattedLonLat = function( coordinate, axis, dmsOption )
This function will return latitude or longitude value formatted as
| coordinate | {Float} the coordinate value to be formatted |
| axis | {String} value of either ‘lat’ or ‘lon’ to indicate which axis is to to be formatted (default = lat) |
| dmsOption | {String} specify the precision of the output can be one of: ‘dms’ show degrees minutes and seconds ‘dm’ show only degrees and minutes ‘d’ show only degrees |
{String} the coordinate value formatted as a string
