consider chaining methods

[skariel]

e.g.

d= self.rdoc.element('div').style(
    background='#AAFFAA',
    ).appendto(self.container)

instead of...

d= self.rdoc.element('div')
d.style(
    background='#AAFFAA',
    )
d.appendto(self.container)

maybe its better with longer names... actually doesn't seem too valuable.
