Fixed Issue 1: picketPlot graphical appearance cannot be changed from
annHeatmap2

Due to bad parsing template in annHeatmap2. So I dumped the default values
into a small (undocumented) wrapper function that is called from both
picketPlot (for stand-alone use) and annHeatmap2 (for a proper parsing
template).
Updated list of undocumented functions

The container 'Undocumented.Rd' now also shows the names of the functions
that are, you know, undocumented.
