Add OAuth support for http streaming reader operator about streamsx.inet

[rohitsw]

Question on how to incorporate outside libraries into builds and operators:
The OAuth feature I am planning to add will require some open source java libraries to be used. The libraries are under an Apache 2.0 license. Users should download the libs themselves and point our toolkit to them whiling building/running.
Some questions:

1. Where do i put the pointers for users to download the libraries? README file?
2. Should I use environment variables in the build.xml and operator Libraries annotation? If so, whats the naming convention for these? "@APACHE_COMMONS_CODEC_LIB@" for example?

Which OAuth version is being supported?
Which OAuth libraries are you planning to use, can you provide a link to the download site.

OAuth1.0a version.
I'm using the oauth signpost library (http://code.google.com/p/oauth-signpost/) as it seems to seamlessly work with the java URLConnection API.
ill add comments and clarifications in the code/documentation as well

Did you look at the Google library, which also supports 2.0?

I did look at it a while back and at the time it did seemed to work only with the google http libraries and did not support the standard one I was using.
