add to the change interface.
Update test apply functions to use an interface rather
than a function type.

Add diff comparison with support for double walking
two trees for comparison or single walking a diff
tree. Single walking requires further implementation
for specific mount types.
Add directory copy function which is intended to provide
fastest possible local copy of file system directories
without hardlinking.
Add test package to make creating filesystems for
test easy and comparisons deep and informative.
