Orientation/Learning Documentation

The code in this pull request comprises of two parts:

1. Documentation as orientation or learning material. Some in class and class-feature note clauses and others in NOTES.txt (which--at it turns out--is not going to be my ultimate suggestion, but simply where we started).

2. Some changes I needed to get EWF to run on my local machine.

in the ascii diagram , the meaning for WSF is not "Eiffel Web Server Gateway Interface" .. this one is for "EWSGI"
WSF would stands for "Web Server Framework", EWSGI (or WGI_ ) is mainly the specification for connectors.
EWF and WSF is standing on top of the EWSGI layer/specification which provides the connectors.
