 Currently I am refactoring the code, and more features like TTL are coming soon. And the installation with cmake will be much more easily.

+=========
 I have created a branch named `pybind11` which provides the basic functions (`put`, `get` and `delete`) now. And the installtion is much more easily!  you can try it if you encounter any installtion issues in the current version of `python-rocksdb`.
 
 The branch is under development and will be released to PypI after I migrate most of the existing features.
