Different letter case scheme

[pzmarzly]

Some identifiers in the screenshot above were underlined by the spellchecker as it cannot see word boundaries. It's not that easy for humans, too, asthisexamplestringhopefullyillustrates. I think it would be better to use snake case (text_box, v_box, on_click, on_input)

Yes, I'll take this into consideration.

I have changed the widget names:

vbox => column
hbox => row
textbox => text_input
