Reference Documentation

[nicholas-leonard]

So I am working to migrate the docs of the main packages to readthedocs.org :

• torch7 (PR merged)
• nn (PR merged)
• image (PR sent)
• paths (PR merged)
• gnuplot (PR merged)
• cwrap (PR merged)
• optim (PR merged)
• trepl (PR merged)
• qtlua (PR merged)

Next I will need to update all inter-repo doc hyperlinks to point to readthedocs instead of github (this doesn't affect intra-repo links). This also includes the doc links in this repo.

• fix inter-doc links

Once the reference documentation is on readthedocs, I will try to find the motivation to finish (or at least continue) the torch manual.
