Taylor diagrams with negative correlations

[blychs]

Currently, MELODIES-MONET is not capable of plotting those.
Having nothing is a mistake, that can lead users to infer a bug that does not exist.
I can think of three solutions:

1. The lazy way: raising a warning when that happens.
2. The NCL way: we would still plot only the 1st quadrant, but print the value of negative correlations.
3. The plotting way (might require some changes at the MONET level): Add capability to plot 2nd quadrant if the correlation is negative. This could be optional for the user.

I think that 3), or a combination of 2) and 3) (up to the user), is the right way to go.
Let me know your thoughts

I asked Gabi and Forrest, and they suggest solution 2. If everyone agrees, I'll move forward with this.
