Allow -n for number_of_lines to be used with -d 'max depth'
Remove depth specific functions, the job is now handled by the mainline
Add depth as a field onto the Node object.
The -e and -v flags allow multiple values. Before values after the first
were ignored. This change allows the user to specify multiple regexs and
have them all applied.
-t = Show summary of types
-e = Filter by regex
allows you to specify a file type like -e "\.txt$"
Change behaviour of '-f' flag - it now counts only files. Before it
counted files & directories. This was needed for compatibility with
the new '-e' filter flag
