 * 1) Launch QGIS
 * 2) Load the data layer.  Using menus at top of screen select LAYER -> Add Vector Layer
 * 3) Press Browse button
 * 4) Navigate to the folder holding the sample datasets and select busstopsall.shp and press Open button
 * 5) QGIS will automatically zoom to the extent of the bus stop features
 * 6) Run the buffer process from the menu: TOOLS -> Geoprocessing Tools -> Buffer(s)
 * 7) Set the Input vector layer to busstopsall
 * 8) Enter Buffer distance of 200.  This will be 200 metres.
 * 9) Set the Output shapefile by pressing Browse button.  Navigate to the data folder and enter the new filename as busstops_200m_buffer.shp.  Press Save button to select that filename.
 * 10) Press OK button to run the process.
 * 11) After running, the system asks Would you like to add the new layer to the TOC? select Yes and the resulting shapefile will be added as a layer in your map view.
 * 12) Buffer(s) window remains open.  Press Close to close the window.
 * 13) Reorder the layers so the resulting buffer polygons layer is on the bottom of the layer stack.  Click and drag the busstops_200m_buffer.shp layer to beneath busstopsall.
