We currently only have one 'visit' method that accepts a filter for returning
results and a filter for recursing into the tree. You can use and
combine multiple filters like so:

    root = Path('...)
    for path in root.visit(AND(isdir, nolink)):
        # iterates over all non-link dirs in the tree (breadth-first)

or

    for path in root.visit(AND(isfile, endswith('.txt')), nodotfile):
        # iterates over all '*.txt' files but not recursing into ".*"

and so on.  This proved to be flexible and convenient and mostly avoids
the need for multiple walk-methods.
