--------------------------------------------------------------
Add Spark driver for generating data using new data generator. Update
build.gradle to add Spark and data generator dependencies. Update README.
[~jayunit100] Can you take a look? At this point, we need to converge the data
models, update the Pig scripts, and add a MapReduce driver.
Note that we may want to clean up the dependencies in gradle so that we don't
include the spark assembly jar in the shadowJar (that is provided by Spark).

> BigPetStore uses synthetic data as the basis for its workflow. BPS's current
> model for generating customer data is sufficient for basic testing of the
> Hadoop ecosystem, **but the model is very basic and lacks sufficient
> complexity for embedding interesting patterns into the data**.
> As a result, **more complex, scalable testing such as testing clustering
> algorithms in Mahout on non-trivial data or multidimensional data with
> factors influencing it** is not currently possible.
> Efforts are currently underway to incrementally improve the current model
> (see BIGTOP-1271 and BIGTOP-1272).
> To create a model that can that incorporate **realistic, non-hierarchichal
> patterns** and input data to generate rich customer/transaction data with
> interesting correlations will require a re-imagining of the current model and
> its framework.
> To support the improvements to the model in BigPetStore, I have been working
> on an **alternative ab initio model, developed from scratch**. Since the
> development of a new model involves substantial R&D work with more
> specialized tools (mathematical and plotting libraries), I'm doing the
> current work outside of BPS using the iPython Notebook environment. Due to
> the long time frame, the model will be developed on a separate timeline to
> prevent slowing the development of BPS.
> Once the model has stabilized, I will begin incorporating the model into BPS
> itself. One option is to implement the model in using Scala for clean
> integration with **spark** which is likely to play an increasingly important
> role in the hadoop ecosystem, and thus will be an important part of
> bigpetstore as a test/blueprint app.
