Open Moran scatterplots with local Geary

[jkoschinsky]

Re. Local Geary (univariate and multivariate): To make it easier to interpret and see the distribution of values in a multivariate setting, we discussed two ideas:

-- the Moran scatterplot view was just extended with the two small plots to the left and right of the main plot for selected and unselected observations. Use this same setup to display up to 5 plots (2 left and right + middle plot) for the variables used to construct the multivariate local Geary.

--an alternative would be to use the view of the scatterplot matrix but instead of keeping the current matrix, display multiple "independent" scatterplots that reflect the variables used in local Geary.
