Factory function to create a dict-like object[s] supports merge operation
from a dict or any other objects.
.. seealso:: :func:`m9dicts.make`
:param obj: A dict or other object[s] or None
:param ordered:
Create an instance of OrderedMergeableDict instead of MergeableDict If
it's True. Please note that OrderedMergeableDict class will be chosen
for namedtuple objects regardless of this argument always to keep keys
(fields) order.
:param merge:
Specify strategy from MERGE_STRATEGIES of how to merge results loaded
from multiple configuration files.
:param _ntpl_cls_key:
Special keyword to embedded the class name of namedtuple object to the
dict-like object created. It's a hack and not elegant but I don't think
there are another ways to make same namedtuple object from objects
created from it.
:param options:
Optional keyword arguments for m9dicts.convert_to, will be converted to
the above ac_\* options respectively as needed.
