Please add an option to output the numerical values

Hi,
This visualization tool is really a big help. But I have encountered some issue when using this tool.
Currently, this tool only outputs the images and everything seems to be fine if the input to the neural network is a real image. But when the input is not a real image(assume that the input is a tensor of size NNC, where C=4 is the number of channels; note that the input is just a feature of 4 channels, not a real image), the output of tf_cnnvis.deconv_visualization will be of little use because the output feature is interpreted as an RGBA image.
Therefore, I propose this issue to add an option to output the numerical values besides the images. Maybe you can add a Boolean flag "output_value" in the function to decide whether the numerical value of the corresponding images will be shown.
Thank you in advance.
