Change m_S^2 --> xi_F to address referee point 1.
Added explanation that if entry zero is not set then we use the gauge coupling unification scale for M_X.
Addressed referee point 4 by explicitly stating the EWSB outputs.
I also added a sentence emphasising only when we output soft Higgs masses
can mu, m3^2 or xiS be set, thus helping clarify confusion behind
point 2.  Also fixed typo from previuos change (xi_F -->xi_S).
entry --> entries
usual --> dfault.
To address referee's point 5 and Ben's catch about QEWSB:
promoted MSUSY footnote to main text and added caveat about the special
SOFTSUSY option to change this.  referenceing MSSM manual fore details.
Minor grammatical and formatting edits to Appendix A.  Footnotes placed after punctuation and new Eqs. A1-A2
Moved Eqs. A1 and A2 to appear earlier in Appendix A
Minor edits to paragraph below Eq. (38) to point reader to relevant EWSB conditions
Minor grammatical corrections to text following Block EXTPAR
Fixed two typos in Appendix A
