SparseStream Example

[InquestGeronimo]

Adding the SparseStream App to the examples directory. This app allows the user to stream real-time finance-related tweets and classify them using custom sparse models classifying topic and sentiment.. In order to do QA checks to run the Twitter API, we will need to get NM Twitter tokens for API access.

The config file has placeholder models while I upload them to sparsezoo (in progress).
