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 code calculating the width of a row to use vs the width of the
terminal wasn't quite right.
If we had 2 long filepaths one at the top of the dir tree and one at the
bottom the old code would shorten both equally. This doesn't make sense
as the one at the shallowest part of the tree would have used less
screen real estate and so should show a longer part of the filepath.
Remove note about 'height' and '-h being help' because it confused
people.
Add text to explain default height is terminal height - 10

For some unknown reason mac takes offence to searching for
'test_dir_unicode'. 'test_dir_hidden' seems to work fine.
This isn't a proper fix as I've just hacked round the problem. Ideally
I'd need a mac user to do some investigation.
Because apparent_size uses the test files created in /tmp it needs to be
in the test_exact_output where those files are copied. Otherwise the files
may not be there when the test is run.
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
Move apparent size test to 'test_flags' file. We can no longer test the
exact output of this test as it changes too much on different filesystems
Move common code to shared initialization function in test_flags.rs
The old code was subtly different in the way the root node worked. This
changed in the v0.6.0 version when dependencies were removed. The code
to handle file count was never updated
