- change libfaiss_c.a libgpufaiss_c.a targets to only include wrapper
impl
- include libfaiss_c.a on c_api `make all`
- build libgpufaiss_c.so with libfaiss_c.a instead of faiss_c .o file list

CMakeLists.txt, so we can install the libs and headers with make
install.

leftover include file

* [c_api] leverage index downcast

- make index downcast declaration+definition possible with macros
- use macros on existing index types

* [c_api] Add Index IO interface

- new header index_io_c.h for access to the index_io.h API
- function`faiss_write_index` and overloads for dumping index to a file
- function`faiss_read_index` and overloads for reading index from a file
- function`faiss_clone_index` for cloning an index

update faiss.py to enforce less strict check of error message

thanks. Also addresses #392

Not tested but looks legitimate + better than previous state in any case ;-)

* :update Readme to include conda install info

* move to INSTALL.md

* Add C API

* Add installation instructions for the C API

- support on-disk IVF
