MAINT: Filled in description fields, etc.

1. Populated description and long_description fields to `setup`.
2. Added `install_requires = ['numpy', 'cython']` to `setup` call.
3. Updated `build/always_include_files` in `conda-recipe/meta.yaml` to include cached files, both for Python 3 and Python 2, to ensure that `conda remove mkl_fft` removes all the artifacts from the conda environment.
4. Updated `README.md` to states steps required to install `mkl_fft` using `pip`.
