Java API 

...Fixed small bug in ClassBasedRowReader which caused problems when data were read into Java beans. Added type converters for boxed Java primitive types. Added SparkDriverJavaUtil with methods which help in development of Java applications. fixes #11
I wonder if JavaConversions doesn't have something to convert arrays to Scala Seq, but maybe I'm wrong. Anyways, as above, this and other calls like that would be better to have in the `JavaAPIHelper`.
