API Doc not refreshed on website

[eric-haibin-lin]

I compared the API documentation in the source code and on the website. They are different. Is the website refreshed at all? Specifically, the sparse embedding op on website doesn't have the "note" section in the source code:

http://mxnet.incubator.apache.org/versions/master/api/python/ndarray/contrib.html#mxnet.ndarray.contrib.SparseEmbedding

https://github.com/apache/incubator-mxnet/blob/master/src/operator/tensor/indexing_op.cc#L269-L277

The newly added LayerNorm also does not appear in the website.

The site will need to be refreshed for these to appear.
