Description

I have found this method extremely useful when implementing my own strategy for inferring a schema from parsed json. For now, I've actually copied the method right out of the JsonRDD class into my own project but I think it would be immensely useful to keep the code in Spark and expose it publicly somewhere else- like an object called JsonSchema.
