%
% Function converts a traditional matlab figure into a Live Editor figure.
% Input: fig - is either a figure handle or a figure filename.
%        xLim - x-axis limits (optional).
%        yLim - y-axis limits (optional).
%        legendPosition - legend position string (optional).
%        figSize - figure Size. Increase the size if axes labels don't fit.
%        tight - tight fit the figure and its labels if axes labels are cut
%                off. This property messes up legends if multiple figure
%                are displayed side by side.
% Output figH - a figure handle of the Live Editor figure.
%        axes - an axes handle.
