Fixed transpose issues. No works same as other colt matrix using viewDice. This will create an view (not a copy) of the orignal dataset that refects modifications of the original. This is the same behaivor of viewDice in other colt matrix implementations
removed old get row count since this is already present when extending double matrix from colt
Please check these two functions: setNrRows and setNrCols. I think they are invalid
