Added legend and updated names of module current graph to setup splitting of graph
split graphs for module leakage current
set root to select correct time axis format
Updated rolling vector to make the vector time ordered and add values from back
Updated rolling vector to allow it to start from empty and fill rather than forcing an initialization value
allowed access to rbegin and rend
Updated all graphs to deal with new rolling vector type.  updated some handling in rolling vector for empty vectors.  broke update current
Fixed issue with currentupdate.  something else in plots broke
Updated plotting and scaling on graphs.  scaling broken for fin currents
fixed bug in fin current graph due to old rolling vector class construcor
Fixed issue that was only displaying one graph (plotted axis for only first graph)
