batch sampling from softmax distribution

[ghennequin]

It would be great to have a function that does batch sampling of the (batch) output of a softmax (i.e. if the output of the softmax is MxN where M is the number of samples and N is the number of output categories, and therefore each row contains the probabilities for a categorical distribution, then we want to return an MxN matrix where each row is the one-hot encoding of a sample of the corresponding distribution).

@ryanrhymes why did you close this?

oh, missed your comment. I closed some issues which do not seem active and critical. I also consulted jianxin who told me there are no similar APIs in other frameworks. But please do feel free to reopen it if you think this is an important feature.
