Create coordinates data structure from components

CA coordinates store lines as a series of comma delimited lat,lon pairs which themseleves are delimited by ; and enclosed by [ ].
This takes coordinatesLatitudeDecimalFrom,coordinatesLongitudeDecimalFrom, etc keys in the content tree and transforms them into CA compatible coordinates. Also this method needs to be called after _processBundles.
