restore_editfiles(usernamespec,matlabrev)

function restore_editfiles(usernamespec,matlabrev)
%RESTORE_EDITFILES reloads the .m files to the file editor if you accidentally close it, or when switching revs
%   if run w/ no arguments, reloads .m files that were open at the end of the last session
%
%   usernamespec    if you specify this, it will load the files previously edited by that user, 
%                   otherwise gets login ID of current user (Windows)
%   matlabrev       if you specify this, it'll open the files last edited in that version 
%                   (handy for switching from R13 to R14)
%
%   Matlab R13 & R14, Windows only ... if .ini/.xml file formats are similar in mac, just need to put in proper location
%
%   Note: not much error handling
