This should help dealing with multi-part data
```xml
<dependency>
<groupId>com.sun.jersey.contribs</groupId>
<artifactId>jersey-multipart</artifactId>
<version>1.8</version>
</dependency>
```
A sample of java REST implementation
```java
@POST
@Path("multipart")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(Servlets.JSON_MEDIA_TYPE)
public String processMultipart(@FormDataParam("meta") String jsonMeta,
@FormDataParam("data") InputStream inputStream) {
return null;
}
```

Might not be needed in intg module. Please review.

Typo

I think it's better to use the Guava Function interface or
java.util.Function interface as it's exactly same.

> * _AtlasImportTransformBuiler_ has new classes that support transformations.
