nested_dict
is a python library which extends collections.defaultdict to allow dictionaries with multiple levels of nesting to be created on the fly:
```
from nested_dict import *
nd = nested_dict()
nd["a"]["b"]["c"] = 311
nd["d"]["e"] = 311
```
Each nested level is create magically when accessed, a process known as “auto-vivification” in perl.
