multi_anaylsis: comparison to anayltical solution done, v_y <-> mesh, timestep (almost) done, LHS soil search done;

minor datatype changes; multi_analysis: better visualization, minimal_working_example added more cuboids

multiple_analysis v.2 (needs modularization!), robustness (100 sphere incline 20 deg rolls), v_y boxplot done; various helperfunctions added

Added univariate_paired_simultaneaous_confidence_intervals and simpe univariate_sci (NOT TESTED WITH REST OF CODE!)

Added/improved DOCU at multiple helperfunctions; Restructuring: moved datafiles out of the way; minor adjustments

Fixed incline/analysis.py > r_z problem; Fixed helperfunctions.py > -h issue, > Saver access of .csv files

siconos' coordinate system definition done for incline pipeline -- does not really work (see analysis...)
