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.

why not having

glossary: "[<...>]"
   "Apache2 Web Server": "[
                                           ]", EIS: "....."
   "EWSGI" : "[ ....]", EIS: " .. "

so indexed by the term's value, rather than having "term" for each line.
