Updating vtkView
Fixed vtkTools and vtkView to work for all cell,faces, edges.

Changed index for cells, faces and edges to be C,F,E respectively.
Made viewprop, limits, extent as @properties, with error checks in the set methods. Need to finish the limits error checks.
First attempt on saving to a database, have written a very light wrapper on h5py.
Fixed errors. C,F,E works with limits, extent.
Added .cmap for color mapping and .range to set the color range. Need to add colorbar, and more settings as it comes along.
Added a colorbar to the figure.
Updated the example at the bottom of the vtkView. __name__ == __main__
update the requirements.txt file.
Made a notebook that works with updated version of vtkView
