Initial commit

This commit intends to demonstrate the general idea of exactfreqfinder. It has
yet to be arranged into proper modules.

The codes are placed in the folder named *playground*, which runs on a simple
script-generated test case.

The *setup.py* file is still not functioning properly.

Edit information on README.md

It is found that README.md file is pointing to wrong URL address of the
project:

This information is corrected in this commit.
