version 2.4 changes

Trajectory plotting

0. Added support for trajectories

Support added for plotting trajectories in contiguous ragged array format.

Done

1. zorder option added to plotting commands

The plotting order parameter, zorder, has been added to con, vect, stipple and lineplot. Using zorder with a larger number puts the plotted item on top of an item with a lower zorder number.

Done

2. Fix blockfill on pressure plots

A bug in pressure blockplots was fixed.

Done

4. Test release

A test release to fix a bug in the markup in the README.txt file for cf-plot

Fixed

5. traj - fix missing trajectories

An incorrect loop index was used leading to not all teh trajectories being plotted.

Fixed

6. vect - magmin keyword added

The magmin keyword was added to vect. Any vectors with a magnitude less than this aren't plotted.

Done

7. con - model level data not properly labelled

Contour plots of latitude or longitude vs model level number weren't proper labelled on the y-axis.

Done

8. con - polar plot labels

If a polar plot is made and the axis_label_fontsize is set to zero then the longitide labels are no longer plotted. Previously they were plotted but still appeared on the plot wven though they had zero size.

Done

9. con - Rotated pole data change

Contour plots using rotated pole data - if the longitudes and latitudes for each point are supplied as 2D arrays in auxiliary coordinates then these are now used for making a contour plot. Previously the rotated pole coordinate system was used to generate the longitudes and latitudes for the contour plot.
