rename lenet dir to mnist
add mnist autoencoder example necessities (sigmoid cross entropy loss
layer, sparse gaussian filler)
enable DataLayer to output unlabeled data
mnist autoencoder test proto bugfix: add sigmoid layer before loss
make solver able to compute and display test loss
change lenet dir to 'mnist' in docs
mnist_autoencoder_solver cleanup
add sigmoid cross ent layer unit tests
clear sigmoid top vec at initialization
change to correct next layer id for merge
Merge pull request #330 from jeffdonahue/mnist-autoencoder-example

add ShareTrainedLayersWith method and use for test net in solver
remove unnecessary return from void set_generator
pass caffe rng ref into variate_generator constructor instead of having
caffe rng adopt its state
remove now unused set_generator and related code
