> I agree with @wuchong , that we should follow the example of Gelly and
add the flink-table-examples JAR file to the opt folder.
@fhueske Thanks for your review.
IMO, directory style below is reasonable:
* `examples` directory only contain example jars
* `opt` directory only contain optional library jars
* `lib` directory only contain library jar that must be load in runtime
The `opt` directory is noisy, that contains lib jar and example jar:
```
flink-cep-scala_2.11-1.3.0.jar
flink-gelly_2.11-1.3.0.jar
flink-metrics-statsd-1.3.0.jar
flink-cep_2.11-1.3.0.jar
flink-metrics-dropwizard-1.3.0.jar
flink-ml_2.11-1.3.0.jar
flink-gelly-examples_2.11-1.3.0.jar
flink-metrics-ganglia-1.3.0.jar
flink-gelly-scala_2.11-1.3.0.jar
flink-metrics-graphite-1.3.0.jar
```
