Modified build.sbt to run assembly without testing.
Adding first Matrix.scala tutorial.
Multiple SequenceFiles paths

Added case class to handle multiple input of sequence files.
Please note: If someone would like to have multiple inputs of some other scheme, he would need to implement the same exact line for the other schemes.
We found no better way to do it without refactoring all the input schemes. Also, that was the way suggested by Oscar.
