# This class is used by Import/Export to move files and folders from a source folders into a target folders
# that can already have the same folders in it, resolving in a merged folder.
#
# Example:
#
# source path
# |-- tree
# | |-- project
# | |-- labels.ndjson
# |-- uploads
# | |-- folder1
# | | |-- image1.png
# | |-- folder2
# | | |-- image2.png
#
# target path
# |-- tree
# | |-- project
# | |-- issues.ndjson
# |-- uploads
# | |-- folder1
# | | |-- image3.png
# | |-- folder3
# | | |-- image4.png
#
# target path after merge
# |-- tree
# | |-- project
# | | |-- issues.ndjson
# | | |-- labels.ndjson
# |-- uploads
# | |-- folder1
# | | |-- image1.png
# | | |-- image3.png
# | |-- folder2
