Duplicated client requirements text

[mbtaylor]

Appendix D.0.1 more or less duplicates Section 2.1.7.
Also:

• D.0.1 is a subsection of the Appendix on Exoplanets, which it's not really relevant for
• I don't know why I'm the only person to get my name in a section heading

The scientific cases have been collected from some contribitor, including yourself, and we keep track of them in the section titles. For some reasons, your name kept in place. I'll remove it.

These contributions are too much long to stay in the usecases section. This i why I moved then in the appendices letting just a summary in place. Your contribution being very concise, the summary does not differ that much from the whole one.

Anyway, I propose to remove the whole contributions from the appendices in order to shorten the document and to facilitate the review task.

Thanks, that looks good to me.
