/**
* Core Spark functionality. [[spark.SparkContext]] serves as the main entry point to Spark, while
* [[spark.RDD]] is the data type representing a distributed collection, and provides most
* parallel operations.
*
* In addition, [[spark.PairRDDFunctions]] contains operations available only on RDDs of key-value
* pairs, such as `groupByKey` and `join`; [[spark.DoubleRDDFunctions]] contains operations
* available only on RDDs of Doubles; and [[spark.SequenceFileRDDFunctions]] contains operations
* available on RDDs that can be saved as SequenceFiles. These operations are automatically
* available on any RDD of the right type (e.g. RDD[(Int, Int)] through implicit conversions when
* you `import spark.SparkContext._`.
