Adding example in the node description..

[GoogleCodeExporter]

Please describe the purpose and the intended behaviour of the new feature.
Some of the nodes are a bit hard to comprehand in particular without some 
specific examples. Perhaps, adding a link to some on-line examples would 
be a nice feature to have.

For instance in the upivot node, I was not sure how to get it to work. I 
figured out that you needed to add a capturing group and that the 
remainder would be the column name, but it would have been easier to 
figure out with some examples.

If it has connection to other parts please state it too.
