Added addition, subtraction and multiply by scalar to DenseVector.scala and
SparseVector.scala
Small change to add vector operations. With this small change, can now do
things like:
```scala
val v1 = DenseVector(0.1, 0.1)
val v2 = DenseVector(0.2, 0.2)
val v3 = v1 + v2
```
instead of what is now has to be done:
```scala
val v1 = DenseVector(0.1, 0.1)
val v2 = DenseVector(0.2, 0.2)
val v3 = (v1.asBreeze + v2.asBreeze).fromBreeze
```
Did not add a test, not sure if I should add a test to any Suite for such a
small change? There is no JIRA issue on this. @chiwanpark
