Trying to add syntaxhighlighting to code snipits

Build is using sbt:

    sbt publishM2 

Add this to you pom.xml:

This is how to generate jsonSchema in code using Scala:

```scala

    val objectMapper = new ObjectMapper

    val jsonSchemaGenerator = new JsonSchemaGenerator(objectMapper)

    val jsonSchema:JsonNode = jsonSchemaGenerator.generateJsonSchema(classOf[YourPOJO])

    val jsonSchemaAsString:String = objectMapper.writeValueAsString(jsonSchema)

```

And using Java:

```java

    ObjectMapper objectMapper = new ObjectMapper();

    JsonSchemaGenerator jsonSchemaGenerator = new JsonSchemaGenerator(objectMapper);

    JsonNode jsonSchema = jsonSchemaGenerator.generateJsonSchema(YourPOJO.class);

    String jsonSchemaAsString = objectMapper.writeValueAsString(jsonSchema);

```

Backstory

--------------

Recently we needed to support POJO's using polymorphism like this:

```java

    @JsonTypeInfo(

            use = JsonTypeInfo.Id.NAME,

            include = JsonTypeInfo.As.PROPERTY,

        public String parentString;

    }

```

This is not supported by the original [jackson-module-jsonSchema](https://github.com/FasterXML/jackson-module-jsonSchema).

I have spent many hours trying to figure out how to modify/improve it without any luck,
