Added ability to plot flows in mulgrid layer_plot() method
Renamed mulgrid layer_plot_flow() method to plot_flows()
Added mulgrid plot_colourbar() method, and used it in layer_plot() and slice_plot()
Added ability to plot flows in mulgrid slice_plot() method
Bugfixes in mulgrid slice_plot() and layer_plot()- block names and flow arrows weren't being drawn at the right elevation for some surface blocks on slices; block index for flow arrows wasnt being calculated correctly
Altered calculation of connection node list in mulgrid add_connection(), so that node list is always consistently ordered
Bugfix in slice_plot() and layer_plot()- new plot_flow() method was being called even when no flows are to be plotted
Added t2grid calculate_connection_centres() method
Added flow_arrow_width parameter to mulgrid layer_plot() and slice_plot() methods
Rewrote t2grid flux_matrix() method, using constant or linear flow fitting over each block and pseudo-inverse matrices to assemble into global flux matrix
Rewrote calculation of vertical connection centres and normals in t2grid calculate_connection_centres()
Added flux_matrix parameter to t2listing write_vtk() method, so flux matrices calculated for slice or layer plots can be re-used for write_vtk()
Changed name of mulgrid slice_plot() and layer_plot() flow_key_pos parameter to flow_scale_pos
Added documentation of flow plotting options in mulgrid layer_plot() and slice_plot() methods
Added documentation of t2grid flux_matrix() method
Updated user guide date
