#224 - Use external or embedded (if external Apache Cassandra is not available) for Cassandra examples.

Browse Source 
We now check whether an external Apache Cassandra instance is available at localhost:9042 and use it to run the examples. Otherwise, if no external Apache Cassandra instance is available, we start an embedded Cassandra instance.

The test cases in `PersonRepositoryIntegrationTest` oppose a plain `List` based query method with one that uses a `Stream` and shows how the former pulls all data into memory first and the iteration is done over the pre-populated list. The execution of the `Stream`-based method in contrast shows that the individual elements are read and converted while iterating the stream.
## Preparation
### Install Cassandra
Before we can start we have to install Cassandra, e.g. via brew on Max OS.
More details can be found here: https://wiki.apache.org/cassandra/GettingStarted
### Start Cassandra
```
/usr/local/bin/cassandra -f
```
That should be enough to get you started.
Now you can simply type ```mvn clean install``` to run the example.
