Statement of Requirements

Due to the exploritive nature of this project it was decided that a traditional Statement of Requirements, broken into concrete functional and non-functional requirements, was not appropriate. Instead we produced a list of features we decided were essential to a good SLI application and a list of features which would be desirable in an SLI.
