More work on introduction, and made Z3 in the fancy font with double lines
More on introduction done. I think the basic intro is there now: it's mainly motivation and saying what else is out there. Thats probably all we really need though. Needs tuning, I'm sure.
added further explanation of thresholds. may need to revisit this.
typos and style.
manual: tiny typo fixed.
added DrBarPars masses to printall().
removed Z3 condition for adding the two loop tadpoles, but reinstaed the tachyon condition.
This needs to be tested still.
removed Z3 condition from around two loop additions to higgs masses.
This still needs testing.
Added new warning on Higgs potential.  Included new boolean higgsNoMin() in physpars.{h,cpp}; new flagHiggsNoMin, loop function h(), and VhAtMin() routine in nmssmsoftsusy.{h,cpp}.  Warnings called at end of rewsbTreeLevel() and rewsb() in nmssmsoftsusy.cpp
Changed name of log function h(double mass) --> looplog(double mass) and made private member of NmssmSoftsusy class.  Removed cout statements in VhAtMin
use fast array initialization

However, I think the arrays DMS, DMP, DMSB, DMPB don't need to be
initialized, because all their entries are set within effpot_().
