Issue 111: change all examples to eliminate deprecated class.

[jplflyer]

Use of the curlpp::Cleanup class is commented as deprecated in the include file, but it's being used in all the examples. This commit changes all of them to use

curlpp::initialize();
...
curlpp::terminate();

In a few places, I also fixed inconsistent indentation within the file, but I didn't try to fix different indentation styles across all the examples.

Hi @jplflyer , your fix is accorded to the Cleanup class documentation, so I'm OK with it.
But why your commit have so many differences (spaces, empty lines, line returns...) ? Can you revert it, please ?
Also please remove commented code, and unnecessary comment. Just keep the calls to initialize() and terminate().

Thanks for your contribution

I entirely removed the code I commented out. I'd left it in there for historical purposes, but it's gone, with the associated comments.

It looks like my IDE automatically removes trailing whitespace in C++ code. I didn't know it was doing that. That is probably the explanation for many of the extra changes.

I don't have time to spend another 2 hours on this right now. Deadlines at work and deadlines at night. Perhaps you're happy with this the way it is. Perhaps you will leave this dangling, and if I ever get time, I can figure out how to leave your trailing whitespaces alone, but that won't be this week.

Thanks for the removing of comments. But I prefer to wait you remove all remaining spaces differences, because it can create some merge conflicts when merging with other contributors work.
Thanks for your understanding.

Don't you want to return retVal here ?
