Support Empty List Path In get

squatched · squatched · commit a673d24e727d · 2024-05-31T14:16:20.000-05:00
Solves Issue dpath-maintainers#193. Currently, dpath.get() works with a path of '/' by returning the value of the object passed in. This behavior is not reflected with an empty list. Now, passing an empty list to dpath.get() will behave the same way (returning the root object value).
