Function: Plot images when `kur data -n 1 -plot mnist.yml`

[EmbraceLife]

Hvass tutorial 1 has plotted a few images before building anything I can do this using kur plot mnist1.yml to plot 9 images

After training, plot 9 images again to see how well the model is doing make a plot hook in training section or evaluation or test section

Solution1: for mnist and cifar datasets, to print out dataset and print out images:

• kur -vv data -n 1 cifar.yml or kur -vv data -n 1 mnist.yml
• for other datasets, plotting is disabled.
• see the commit
• see the __main__.build() for key details

Now, to print out a number of samples (images) while plotting the images for displaying:

kur data -n 1 -plot cifar.yml
