@diff.tree - show file differences between 2 directories
Given: 2 directory names
If desired, list files that do not exist in one of the directories.
For the files that exist in both directories, list those that differ.
If desired, show the actual differences.
This is similar to @diff.files, which only looks at files in a
specified list.

-save : save actual file differences (txt and pdf)
-show : show actual file differences
-show_list_comp : show any pairwise differences in file lists
(terminate after showing comparison)
-skip_data : skip binary diff of select data files
(.BRIK, .dcm, .BRIK.gz)
-verb LEVEL : set verbosity level (0,1,2)
(default 1)
-diff_prog PROG : use PROG to show diffs (e.g. xxdiff, meld)
-xxdiff : use xxdiff to show diffs
-X : implies -xxdiff -ignore_missing
