Adapt tower example to commit 096fb02e2d0637a87ad22a7b776a5a71dfb980a8
Add model suffixes to more variable names in tower example

For the sake of coherence.
doc/paper.tex: introduce command \mathematica

Its definition is Mathematica, as is capitalized on
http://www.wolfram.com/mathematica/ .
doc/paper.tex: insert \@ between a capital letter and \xspace

For a correct intersentence space.
doc/paper.tex: add macros
doc/paper.tex: follow up Peter's comment
doc/paper.tex: add section "Flexible Applications"
disable GSL default error handler and check alloc function return types

The default error handler calls abort().  Since we check the return
types we will catch those errors.
use Broyden instead of Newton as it is much more stable

I just did a CMSSM parameter scan over tan(beta) from 1 to 45.
The newton method fails for some points with high tan(beta) and
is much slower than Broyden.
test Broyden method as well
remove additional space
make loop orders configurable and solve EWSB eqs. at susy scale
Merge remote-tracking branch 'organization/development' into higgs-study
