monkeypatch 'globmatch' function onto pathlib2
#
# monkeypatch to add 'globmatch' function to PurePath, which implements
# the same style of matching that glob supports (which is different
# from what match supports)
#
# Same license as pathlib2 (MIT license)
#
from __future__ import print_function
from pathlib2 import PurePath,PurePosixPath
# Private imports for patching
