Biodiverse now calculates the CANAPE super class

Since version 4.3, Biodiverse has calculated and plotted the CANAPE results when the relevant calculations have been run. 

However, it did not calculate the super class when first implemented. Now it does.

From version 5, Biodiverse calculates all CANAPE classes when a randomisation is run for an analysis that includes phylogenetic endemism and relative phylogenetic endemism.    

Note that the CANAPE classed are only updated after at least one randomisation iteration has been run.  If you have an existing randomisation then you can run one more iteration to trigger the calculation.  Otherwise you can run a new randomisation with the same settings.  This should not take long for most analyses, assuming they are consistent with the sizes of data sets in existing publications.     

If you are wondering why it was not plotted in the first place, it was largely because the plotting system needed some re-engineering to allow for additional legend labels.  This was done when the z-score and p-rank plotting was implemented, a little while after the initial CANAPE plotting.
