[Paraview] paraview web architecture

[Daniel Zuidinga]

Hi once again,

what's a good way to learn paraview web? I am still struggling a a bit 
with it's architecture. Protocol.py is the entry point? When I want for 
example to change the default background color for all renderers where 
do I have to look? Is this set once or for each renderer?

Another thing I would like to change is that I can open a file from 
client inside a running pv web session so that I can load pv web upfront 
and load files without this long wait time.

best regards
Daniel
