Fixes a bug in `export_fig` on Max OSX 10.9 Mavericks, ghostscript 9.07 from homebrew (and MATLAB R2013a).
%GHOSTSCRIPT Calls a local GhostScript executable with the input command
%
% Example:
% [status result] = ghostscript(cmd)
%
% Attempts to locate a ghostscript executable, finally asking the user to
% specify the directory ghostcript was installed into. The resulting path
% is stored for future reference.
%
% Once found, the executable is called with the input command string.
