adjusting 2D gnuplot plots for new grid interpretation (rotating_cone test is a good example where now the signal is centered, while previously it was shifted)
adjusting gnuplot output for 1D plots (xrange and forced histeps style)
converting asserts into exceptions in output gnuplot
adjusting test paper_example_2 to new grid interpretation
adjusting test mpdata_fct_1d to new grid
adjusting yet more examples to new grid; adding histeps emulation for 3D gnuplot plots
updating TODO
