Open an existing outpack root. This returns a "root" object, which can be passed through to various outpack functions. The root object is the same as that returned by outpack_init and will be documented once the interface stabilises.
outpack_root_open(path, locate = TRUE)The path to look for the root; must be an existing
directory. Use NULL (or . or getwd()) for the current
directory.
Logical, indicating if we should look in parent
directories until the root is found (similar behaviour to how
git can find its root directory from any directory below the
root).
An outpack_root object; treat this as an opaque object
for now.
