A method to plot and/or return the posterior of the skewness parameter for models in BALD.

`object`	The object of type `AnnualAggLossDevModelOuput` from which to plot and/or return the skewness parameter.
`plotDensity`	A logical value. If `TRUE`, then the density is plotted. If `plotTrace` is also `TRUE`, then two plots are generated. If they are both `FALSE`, then only the statistics are returned.
`plotTrace`	A logical value. If `TRUE`, then the trace is plotted. If `plotDensity` is also `TRUE`, then two plots are generated. If they are both `FALSE`, then only the statistics are returned.

The skewness parameter does not directly correspond to the degree of skewness. However, all else being equal, a larger (in magnitude) skewness parameter indicates a higher degree of skewness, and a skewness parameter of zero equates to zero skew.

Mainly called for the side effect of plotting. But also returns a named array with some select quantiles of the posterior for the skewness parameter. Returned invisibly.
