Examples on how to connect to the Cypher endpoints from Java with different http libraries

Contributions and Feedback wanted!!!

Infrastructure

There is a CypherClient interface with different implementations for different http libraries.

public interface CypherClient {
    ExecutionResult query(String statement, Map<String,Object> params);
}
```

`ExecutionResult` is an interface with methods: 

````java
public interface ExecutionResult extends Iterable<List<Object>> {
    List<String> getColumns();

    Iterator<List<Object>> iterator();

    Iterator<Map<String,Object>> rowIterator();
}

A Util class takes care of URL handling, JSON conversion and postData and ExecutionResult instantiation.

Jersey Client

See: http://jersey.java.net/nonav/documentation/latest/user-guide.html#client

Uses Client, WebResource and ClientResponse to access the Cypher endpoint.
