Updates to Postprocessor to Include Dual Values for Nodes about calvin

[jdherman]

Nice, it looks like all of these are working! This is great.

One suggestion: you only want to have one "official" version of the files pyvin.py and postprocessor.py. So, update the version in the main folder, and delete the ones in the example subfolders. (You can use the file paths of the examples to run, like this: postprocessor.py /path/to/results/whatever/etc.json)

Since we need nodes.csv and links.csv to do this anyway, I'm wondering if it would be better to get those files from Quinn's export function, and then build the *.dat file from them. (Instead of creating them by hand as a post-processing step). But we can worry about that later.

Another tip for the future, if you have questions about changes before merging them into the main repository, you can make the changes in a different branch, push the new branch to github, and submit a pull request. It will seem a little weird because you're asking yourself for permission to merge your own code, but it gives the chance for comments/edits before changes get merged into master.

Nice job!!

Thanks @jdherman

• Yes, using only one copy of pyvin.py and postprocessor.py make sense. Having more copies is not useful when changes are made.
  Actually, Quinn already provides us *.nodes for nodes and *.dat for links with big matrix.After that
• I create our own data.dat file by adding some more parameters, such as k. Quinn told me that I should be able to convert to .csv by changing the extension. If that doesn't work, we can ask him I guess.
• Sounds good, I will try that for future updates.
