Feature Request: dom child iteration via __iter__

[bannsec]

Is your feature request related to a problem? Please describe

Not really a "problem". More that I find it not terribly intuitive to write dom._pfp__children.

Describe the solution you'd like

My natural response to iterating through a list of object is to use something like "for item in dom". In this case, my proposed solution would be to implement __iter__ as simply return self._pfp__children.__iter__().

Describe alternatives you've considered

Currently I just reference ._pfp__children when I want to see the listing.

Additional context

N/A

This makes sense! Thanks for the suggestion

Eventually I want to do something cleaner than prefixing all internal functions with _pfp__ too
