[mlpack-git] [mlpack] [Proposal]Add a function to visualize the results of sparse_autoencoder (#452)

[Ryan Curtin]

I thought about it for a bit... I think this functionality may already exist (mostly).  The `data::Save()` function will save to PGM or PPM using Armadillo's support.  So, if you added a `Parameters()` accessor to `SparseAutoencoder`, maybe this would work:

```
SparseAutoencoder sa(...);
data::Save("encoder_result.pgm", sa.Parameters());
```

Does that do basically the same thing?
