Merge pull request #139 from ffrensch/master

observed as default in legend instead of asimov
update of temapltes files
update of minima for plots with x-axis range up to 1.5TeV
 adaptatons of laegend position
difference in use of whitespace?
make minimum configurable with a ususal -1 option for automatic adjustment. Needs one more iteration so this will be an intermediate commit
adding function minimum in analogy to maximum for automatic adjustment of minima
adding automatic adkustment for mininmum of plot (for MSSM 1D- xsec limits)
increase robustness of x-axis range determination
adding templates for em postfit plots in ttbar control region
having max and min in layout
coreection of indentations
adding minimum function (in analogy to maximum function)
