flag tachyon when calculating DR-bar masses from pole massses
remove trailing newline
use AbsSqrt instead of ZeroSqrt to avoid division by zero
return pole mass instead of sqrt of the magnitude in case of tachyon

Here we assume that the pole mass is closer to the DR-bar mass than
the sqrt of the magnitude of the negative mass eigenvalue.
very minor change to english and added comment about B\mu = 0 claim.
Wanted to make change when spotted or I'd forget. hope doesn't cause merge
problems with Dominik.
Suppress lattice code from releases
Print full name of an author
Add default implementation of Composite_convergence_tester::max_iterations()
Use composite convergence tester in tower example
examples/module.mk: eliminate lattice code
examples/module.mk: add tower to STANDALONE_DIR

so that make distclean cleans the tower directory as well.
Promote Composite_convergence_tester to a template
src/module.mk: export composite_convergence_tester.hpp
remove support for a default parameter point
remove documentation of default parameter point
remove default parameter points from model files
adding default SLHA input file for the UMSSM
exit with an error message if no SLHA input file is given
more initialization
initialize all input parameters
