    Multi-headed attention from https://arxiv.org/abs/1706.03762 via http://nlp.seas.harvard.edu/2018/04/03/attention.html

    Multi-headed attention provides multiple looks of low-order projections K, Q and V using an attention function
    (specifically `scaled_dot_product_attention` in the paper.  This allows multiple relationships to be illuminated
    via attention on different positional and representational information from each head.

    The number of heads `h` times the low-order projection dim `d_k` is equal to `d_model` (which is asserted upfront).
    This means that each weight matrix can be simply represented as a linear transformation from `d_model` to `d_model`,
    and partitioned into heads after the fact.

    Finally, an output projection is applied which brings the output space back to `d_model`, in preparation for the
    sub-sequent `FFN` sub-layer.

    There are 3 uses of multi-head attention in the Transformer.
    For encoder-decoder layers, the queries come from the previous decoder layer, and the memory keys come from
    the encoder.  For encoder layers, the K, Q and V all come from the output of the previous layer of the encoder.
    And for self-attention in the decoder, K, Q and V all come from the decoder, but here it is masked to prevent using
    future values
