Node's size

Simple question without simple answer?
Is there any way of changing node’s size via python?
It seems that there’s no such property as node size.

Some time ago I have discussed this on IRC and at that time it was indeed impossible to do it, but Lukas Toenne committed update, so now we simply have two additional properties of nodes:
node.width and node.width_hidden
Those properties are not available in official 2.65 release, but latest builds have them.

The first one is responsible for width of node when it’s “expanded”, second one when it’s collapsed (hidden).

We can use those properties to read values and set values:

node.width = 100 for example.

Thank you Lukas
