Further changes to HadoopFileWriter. Implemented ability to save RDDs as SequenceFiles and ObjectFiles.
...
1> HadoopFileWriter changed to take class types as constructor parameters (no more generic type)
2> Multiple types of RDD.saveAsHadoopFile() implemented to provide more saving options
3> RDD.saveAsSequenceFile() automatically converts basic types to Writable types before saving as SequenceFile
4> RDD.saveAsObjectFile() serializes objects and saves them to a ObjectFile
5> SparkContext.objectFile() opens the saved ObjectFiles

Cleaner reimplementation of HadoopFileWriter. Introduced TaskContext.
...
1> HadoopFileWriter works correctly with task failures
2> It can also take an user specified JobConf object for configuration settings
3> A Task can now get information like stage ID, split ID, and attempt ID using TaskContext class
4> Minor changes in SparkContext, DAGScheduler and subclasses to allow specification of TaskContext as a parameter
