6th milestone (release 2)

- documentation, re-worded project intro/description snippet for readability.
- usability
-- feedback, re-factored "Match" term logic, to utilize the known quality of the "Match" attribute result.
--- ie. user request: exclude "dose form" verification, if "dose form" is present in attributes.
-- feedback, re-factored "Match" term ambiguous report logic, in-order to preserve the rule context.
--- ie. user request: attach "ambiguous" to rule match, instead generic ambiguous approach.
