[SPARK-5321] Support for transposing local matrices
Support for transposing local matrices added. The `.transpose` function
creates a new object re-using the backing array(s) but switches `numRows` and
`numCols`. Operations check the flag `.isTransposed` to see whether the
indexing in `values` should be modified.
This PR will pave the way for transposing `BlockMatrix`.
