Direction to install tods in China.

[guanchuwang]

The speed of downloading dependencies from pypi.org will be pretty low in China. You can download the dependencies from pypi.org's mirror site following this Direction:

1. Git this repo to your local directory.

2. Download this tods_install.txt, and put it in the directory tods (not tods/tods): tods_install.txt

3. Change its name into tods_install.sh.

4. Go to the directory tods (not tods/tods), and run sh tods_install.sh

5. Run python setup.py install

6. Run pip install -e .
