new nodes and uses a superclass to avoid redundant code

[bsubei]

made the equalization and backprojection nodes separate. Also created the brightest-pixel threshold node. Since the topic names are params in the launch file, I was able to create launch files that chain the nodes together (with more nodes, we can check all different combinations)

don't merge this yet, more nodes on the way

btw i need to clean up most of these nodes because they're using a lot of configs and variables that are common to all of them (but each node is specific and uses only some of them)

@wfriedl Can you take a look at this since you know the most python?

[bsubei]

thanks for the tips, I'll work on these as soon as I'm back in Chicago

[l0g1x]

test this please

[bsubei]

@wfriedl check it out 7d8b779c5a15581e4ef0815b55a06d17027504f1 I also improved it by using izip instead of just zip, which uses the iterator and avoids creating another big array (or image)

That video you linked was really good, I need to become better at Python :)
