Charts: multi-level treemaps and sunbursts; inclusive box quartiles

Browse Source 
Read, keep and write every cx:lvl of a chartEx category dimension,
build a category tree from runs of parent labels, and draw treemaps as
nested squarified groups with banners and sunbursts as one ring per
level. Box & whisker honours quartileMethod="inclusive" (QUARTILE.INC)
on import, render, save and the chart.options command.
