docs: Concatenate the blocks with another set of blocks.
  
          Note: Assumes that the blocks are already the same shape on the
              dimension being concatenated. A ValueError will be thrown if this
              condition is not met.
  
          Args:
              axis: The axis to concatenate to.
              other_blocks: the other blocks to be concatenated. This is a
                  BaseFrameManager object.
  
          Returns:
              A new BaseFrameManager object, the type of object that called this.
