Extension framework requirements

I've finished making the changes I suggested on Friday.  I also changed the name of this document from 'Framework Requirements' to 'Extension Framework Requirements' in the expectation that the scope of the Framework Team will be broader than developing the Extension Framework.

I would like to start a new page for a glossary and move the terms defined in the charter and in the current requirements document to this new page.  I suggest we have a table of short definitions with links to more detailed information about each (this will eliminate much of the detail from the three system functions in the requirements document.

After the emails from Peter Peter Reutemann, I have modified the Requirements document to include a statement about the need for component packages to be able to include and specify new actor icons as well as include new ontologies or ontology fragments for classifying the actor in the actor tree.
