New in vedo 2020.4.1

• Fixed pip problem (hopefully solving issue #185 raised by @RizzerOnGitHub)
• Typo in readme fixed (thanks to @danielhrisca)
• Global variable settings.collectable_actors is now obsolete and void.
• Various minor issues have been fixed too.

---

addons.py:

• buildAxes() now admits a header title

• addScalarBar3D() returns self, use self.scalarbar to access the scalarbar
  object (e.g for scaling, rotating and repositioning it)

• makeLUT() renamed to buildLUT() with new examples, which includes
  indicators for NaN's and out of scale values:

  

---

base.py:

• setTransform() -> applyTransform() accepts now a python or numpy matrix
  (thanks to @FedeClaudi input)
• added removePointArray() and removeCellArray() methods
• added divergence(), vorticity() methods
• added removePointArray() and removeCellArray() methods (thanks to @Tai-Hsien input)

---

colors.py:

• added ask() method to prompt user input from command line
• added printc(dbg=1) mode to help debugging

---

io.py:

• load() method can load and return normal npy or npz numpy data files

---

mesh.py:

• clone(deep=True), deep can be False to generate a shallow copy of the obj.

---

picture.py:

• polygonize(), create a polygonal Mesh from a Picture by filling regions
  above a specified threshold

---

plotter.py:

• flyTo(), fly camera to the specified point.
• export(), to export scene.npz

---

pointscloud.py

• interpolateDataFrom(), Interpolate over source to port its data

---

pyplot.py:

• removed directedgraph.clean() because it's just wrong (might marginally affect @DeepaMahm)
• added whisker() function to generate whisker-style plots

---

shapes.py:

• added CSpline class, to generate a Cardinal Spline object.

---

New examples:
