ENH: Add test for ParallelCoordinatesView

vtkParallelCoordinatesView was not tested. The lack of a test
resulted in low coverage for vtkParallelCoordinatesView,
vtkParallelCoordinatesRepresentation and SCurveSpline.

This patch also repairs a memory leak in
ParallelCoordinatesRepresentation that was uncovered when the test was
added.

Also, since vtkSCurveSpline is only used in
vtkParallelCoordinatesRepresentation and vtkSCurveSpline did not have a unit
test, this path moves vtkSCurveSpline is moved into Views/Infovis.

NOTE: vtkParallelCoordinatesView has a lot of interactive content. To
improve the coverage, future tests must exercise the interactive parts
of this class. This patch is a minimal effort at improving the
coverage.

Escape StringArray in ArrayCalculator

DataSet that contains String Data array prevents the calculator from working.
This fix just skips those types of arrays and lets the calculator do its work normally.

Introduce Bag Plot and HDR statistic filter.

Add a new type of plot to draw 'bag plots', a bivariate generalization
of the univariate boxplot.
Add a new statistic filter to compute the Highest Density Regions
that can be used to compute a density field used to draw the bag plot.

Add support for the case where the bag is reduced to 2 points.

to create a new column containing initial row names, and use such
a column to name the new columns.

Change the default compression level for PNG to 5.

The available range is 0..9. Recommendation from
'png_set_compression_level - Linux Standard Base' say 3..6 perform as
well as 9 and do considerably fewer calculations.
