%helperPlotPositions returns plot sizes and positions based on screen resolution
%   [REPOSITIONPLOTS,POSITION] = helperPlotPositions() determines whether
%   plot tiling can be supported based upon the user's display resolution.
%   If plot tiling can be supported, REPOSITIONPLOTS is returned as true
%   and POSITION contains an array of vectors of the form [left bottom
%   width height] indicating the X-Y position and size for each plot. The
%   plots are arranged in a 3x2 tiled arrangement. If plot tiling cannot be
%   supported, REPOSITIONPLOTS is returned as false and POSITION is not
%   valid.
%
%   The plots are arranged in the following manner:
%    3x2 Tile
%            Plot 5    Plot 1    Plot 2
%            Plot 6    Plot 3    Plot 4
