This is a quick software hack to lower the administration burden of bitwarden collection permission inheritance.
So far, it has been tested on two instances, one with about 2000 collections, that must inherit the permissions from their "parent" collection.
The tool might look hacky (it is) and perhaps not work properly because of the immense amount of time spent creating it (less than 10 hours from conception to production), so consider this beta stage.
Feel free to open issues if something doesn't work the way you want.
There have been a couple of important fixes into this version (server url config, non existing session keys when using REST api...) and one feature (in-place update of user / group permissions).
Consider all previous versions as alpha versions.
