Almost LGTM. Only need to refine the comments.

- “getting max instance of a sequence” 这个表述令人困惑。
- Stride is the step size by which we slide a window upon the input sequence, and the pooling operation is then applied to each interval independently.

Done. And update the comments in SequencePoolLayer.h, AverageLayer.h and SequenceLastInstanceLayer.h at the same time.

stride --> the step size between successive pooling regions.

| If stride > 0, this layer slides a window whose size is determined by stride, | ||
| and return the pooling value of the window as the output. Thus, a long sequence | ||
| will be shorten. Note that for sequence with sub-sequence, the default value | ||
| of stride is -1. |

the parameter stride specifies the intervals at which to apply the pooling operation.
