'''Takes a QgsVectorLayer and returns the filename to refer to it, which allows external
apps which support only file-based layers to use it. It performs the necessary export
in case the input layer is not in a standard format suitable for most applications, it is
a remote one or db-based (non-file based) one, or if there is a selection and it should be
used, exporting just the selected features.
Currently, the output is restricted to shapefiles, so anything that is not in a shapefile
will get exported.
It also export to a new file if the original one contains non-ascii characters'''
