[SPARK-5486] Added validate method to BlockMatrix
The `validate` method will allow users to debug their `BlockMatrix`, if operations like `add` or `multiply` return unexpected results. It checks the following properties in a `BlockMatrix`:
- Are the dimensions of the `BlockMatrix` consistent with what the user entered: (`nRows`, `nCols`)
- Are the dimensions of each `MatrixBlock` consistent with what the user entered: (`rowsPerBlock`, `colsPerBlock`)
- Are there blocks with duplicate indices
