micvbang.dictutil.get_deep(obj, path, separator='.')

Retrieve the value denoted by path in obj.

This is done by recursively calling obj.get([path_head], None) until the path is traversed, until a value on the path does not have a callable get method, or until the next step in the path does not exist. In case the full path cannot be traversed, None is returned.
