Initial commit
Download Cephes from netlib

Pure mirroring of Netlib's Cephes folder, using the following command:

```bash
wget --no-directories --mirror --convert-links --no-parent http://www.netlib.org/cephes/
```
Extract cephes' multiple tgz into separate folders

Extraction done using the following command in directory `cephes`:

```bash
find . -name "*.tgz" -exec bash -c 'mkdir ${0/.tgz//} && tar xzf $0 -C ${0/.tgz//}' {}  \;
```
Move c9x-complex sub-directory up to match structure

All other tgz have been extracted in their own directory, whereas
c9x-complex went into a sub-directory. This commits makes things
uniform accross all tgz.
Move documentation files to own folder
Copy header file where needed

mconf.h was missing in bessel and polyn. Copied it there
from cmath. This is because cephes usually assume that everything
is unpacked in the same directory.
Add CMakeFiles to build cephes and install doc

The build only links functions for double precision, because the other
precisions cause some name clashes. It also ignores the file for rational
polynomial functions, whose functions' names clash with the simpler polynomials.

When files exist in exact duplicate in several directories,
cmath is preferred, then the folder, then misc

Links to the documentation is added to the local torch documentation.
Wrap a few functions from cprob
Add unit tests
Update README with usage examples
Link to the author
Add rockspec for torch-rocks
Update description in rock
Update URL in rock to point to github

The netlib URL is good, but has no doc about the torch wrappers,
therefore it makes more sense to point to the github repo and its
README.
Initial version of function declaration parsing script
Update parsing script
Add list of functions to parse

Those are a merge between the documentation and the protos.h files,
since both of them ignore some important functions.
Add stub for test generation

Also removed old code for counting functions
Import all double functions

Generated with the current convert.py and list_of_functions.txt
Install all *.lua files instead of only init.lua
