renamefile
Rename a series of files.

Description
renamefile(NAME, P1, P2) renames the files matching NAME, replacing 
the substring P1 by P2. NAME may be a cell array of strings, and may 
contain wildcards (*) and brackets (see expandstr). If P1 is present 
several times in a filename, replaces only the last occurrence. 
 
Examples: 
   renamefile('DSC*.JPG','DSC','myphoto') 
   renames the files 'DSC00001.JPG','DSC00002.JPG',... as 
   'myphoto00001.JPG','myphoto00002.JPG',... 
 
   renamefile('*/DSC*.JPG','DSC','myphoto') 
   does the same in all the directories containing JPG files. 
 
   renamefile('B[1:100,3]*.VEC','B','PIV') renames the files 
   'B001*.VEC' to 'B100*.VEC' as 'PIV001*.VEC' to 'PIV100*.VEC'
