- improved `vtkplotter.pyplot` submodule
- background color now defaults to white
- added `Mesh.idLabels()` to generate cells and point ID labels
- methods like `rotateX().pos()` now operate in left-to-right order (as it should be)
- Text is split into Text2D and Text (for 3D)

- revised plotting
- added matplotlib-like syntax as in `plot()`
- spherical histograms
- background color now defaults to white
- added `Mesh.idLabels()` to generate cells and point ID labels
- added new examples and general cleanup
- circleCI now works for the stable fenics release

- Added shapes Arrow2D and Arrows2D, SphericGrid, CubicGrid

Available backends:
python
from vtkplotter import *
embedWindow('2d')
embedWindow('k3d')
embedWindow('itk')
