Spring Social UsersConnectionRepository/ConnectionRepository implementation for Neo4j.

Using this library you can easily configure Spring Social for an application that use Neo4j as the database server.

1. Add repository

   <repositories>
       <repository>
           <id>spring-social-neo4j</id>
           <url>https://raw.github.com/shanika/spring-social-neo4j/mvn-repo/</url>
           <snapshots>
               <enabled>true</enabled>
               <updatePolicy>always</updatePolicy>
           </snapshots>
       </repository>
   </repositories>

2. Add dependency

   <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-social-neo4j</artifactId>
       <version>0.0.2-SNAPSHOT</version>
   </dependency>

3. Configure UsersConnectionRepository in spring social config

   3.1 Simple usage (no existing neo4j session/sessionfactory)

   @Autowired
   private Neo4jServer server;
   
   @Override
   public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
   
       return new Neo4jUsersConnectionRepository(server.url(), connectionFactoryLocator, Encryptors.noOpText());
   }

3.2 with a shared neo4j session

* 3.2.1 First make sure "org.springframework.social.connect.neo4j.domain" is given at your factory creation 

   ```java
   new SessionFactory("com.mycustom.domains",...,"org.springframework.social.connect.neo4j.domain")
   ```

* 3.2.2 use this in spring social config

    ```java
    @Autowired
    Session session
    
    @Override
    public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
        return new Neo4jUsersConnectionRepository(session, connectionFactoryLocator, Encryptors.noOpText());
    }

    ```
