# formation
# =============================================================================
# A modification of the Livery Class. This Class maintains formation
# XML files (see Blackburn Buccaneer for an example). Files are regular
# PropertyList XML files whose properties are copied to the
# main tree (whereby the node types are ignored).
#
# SYNOPSIS:
# formation.init(<formation-dir> [, <name-path> [, <sort-path>]]);
#
# <formation-dir> ... directory with livery XML files, relative to $FG_ROOT
# <name-path> ... property path to the livery name in the livery files
# and the property tree (default: /sim/model/formation/name)
# <sort-path> ... property path to the sort criterion (default: same as
# <name-path> -- that is: alphabetic sorting)
#
# EXAMPLE:
# aircraft.formation.init("Aircraft/Buccaneer/Formations",
# "sim/model/formation/variant",
# "sim/model/formation/index"); # optional
#
# aircraft.formation.dialog.toggle();
# aircraft.formation.select("take off");
# aircraft.formation.next();
#
