Added dependencies to setup.py

Pyparsing and SQLAlchemy added to project setup. Fixed a typo that
prevented compilation.

Notes:
1. To run setup.py successfully, "setuptools" is required. Download
from: https://pypi.python.org/pypi/setuptools (installation from .tar.gz
is preferred)

2. If you are behind a proxy, add this to your environment variables
before installing PIP:
http_proxy=http://user:password@Proxy:PortNumber

3. Install PIP, instructions here:
http://www.pip-installer.org/en/latest/installing.html

4. To test the setup, run "python setup.py develop".
