kml_open: Open / close a KML file connection

Description

Opens a KML file in write mode and initiates the KML header. The same file connection is further accessible by other kml_*() functions such as kml_layer() and kml_close(). kml_View tries to open the produced file using the default application.

Usage

kml_open(file.name, folder.name = file.name, kml_open = TRUE,
          kml_visibility = TRUE, overwrite = TRUE, use.Google_gx = FALSE, 
          kml_xsd = get("kml_xsd", envir = plotKML.opts),
          xmlns = get("kml_url", envir = plotKML.opts), 
          xmlns_gx = get("kml_gx", envir = plotKML.opts), ...)
