      Slice used in broadcasting matrix blocks for spark, since this slice up a given matrix into blocks. The slice call here returns a single block inside the idx range specified
      Parameters:
        `ixrange` - Index range containing the row lower, row upper, col lower and col upper bounds
        `blen` - The block size specified, this should align with the ranges.
        `iix` - The block row index
        `jix` - The block column index
        `in` - The Cache block to slice out
      Returns:
        A List containing pairs of MatrixIndices and CacheBlocks either containing MatrixBlock or FrameBlocks

      This function will get slice of the input frame block overlapping in overall slice(Range), slice has requested for.
      Parameters:
        `in` - A Pair of row index to assign the sliced block and input frame block to slice.
        `ixrange` - index range
        `blen` - block length
      Returns:
        Returns an ArrayList containing pairs of long ids and FrameBlocks
