Removed some unused code and comments at the top of the ex-script.

A config file is no longer read.

Module docstring changes. This is no longer a script!

Added a copyright notice to the stereochem_analysis auto-analysis.

Added a copyright notice to the stereochem_analysis.py sample script.

Modified the script so that __init__ sets up the class and run() executes the analysis.

This is not implemented on the other side yet.

Converted stereochem_analysis.py into a true relax script.

This now calls the auto_analyses.stereochem_analysi code.

Renamed the stereochem_analysis_config.py file to the stereochem_analysis.py relax script.

Added the relative stereochemistry analysis configuration file.

This will be converted into a relax script.

Added to the auto_analyses the script for determining relative stereochemistry of organic molecules.

This code corresponds to a paper in press. The script will need to be modified to function as an
auto-analysis, and the actual configuration file turned into the real script.

Modified the _auto_analyses.test___init__ module for the auto_analyses package.
