BoundingBoxDataPointsFilter possible bug

[lingerer]

In BoundingBox.cpp line 80：

  const bool x_in = (point(0) > xMin && point(0) < xMax);
  const bool y_in = (point(1) > yMin && point(1) < yMax);
  const bool z_in = (point(2) > zMin && point(2) < zMax) || nbRows == 3;
  const bool in_box = x_in && y_in && z_in;

const bool z_in = (point(2) > zMin && point(2) < zMax) || nbRows == 3;
which nbRows means dimensions.
This code means if the point cloud is 3d,any z range is useless and will be in the box.

The purpose of the code should be if nbRows == 3,let z range involve, otherwise let it be true.

So the code should be:
const bool z_in = (point(2) > zMin && point(2) < zMax) || nbRows != 3;
