% Saves the given figure to the given directory and filename

% INPUTS:
% filename     : [string] filename (without extension)
% [figures_dir]: [string] directory where the file should be saved to
%                The global variable FIGURES_DIRECTORY will be used if figures_dir is not specified
%                If it is not specified, then the current directory will be used
% [actually_save]: [bool] Default: true
% [figure_handle]: [handle] Default: gcf
% [maximize_figure]: [bool] Default: false. Should the figure be maximized before printing the figure
