%   settingsFile:   The settings variable passed to the function for
%                   saving. If no input has been specified, the function
%                   will load an existing file and pass it out to the
%                   calling function. If a setting file does not exist, the
%                   function will generate a file with defalt settings and
%                   then will pass the variables to the calling function.
