WIP: Creating LabelGeometryImageFilter like filter for ShapeLabelMap

Initial work on creating a filter that is like the
LabelGeometryImageFilter but uses the LabelMap framework underneath
specifically the statistics available in the LabelGeometry mirror
quiet closely with the ShapeLabelObject. So this filter wraps that
filter and present an StatisticsImageFilter like interface.
WIP: adding OBB labelmap and filter

Continued adding Shape label object attributes. Also added the
OBBLabelObject, and the associated filter to compute the new
attributes.
WIP: separated code into h and hxx files
tweaking some comments
Adding Shape statistics test on jelly beans
propagate some parameters from LabelShapStatistics filter to
mini-pipeline filters
