I define an input csv file and an output like so in my processing script:

    ##Input_CSV_File=file
    ##Output_Shapefile=output vector

The output shapefile is added to the map automatically when the script is done, but the name of the layer in QGIS  is always "Output Shapefile".  I want to name the layer based on something in the file.  Is there a way to change the name the layer is added with after the script is done?
