Add Python Support

[CodeYan01]

In Python, everything is accessed via subscripts, no dot notation. Please add a configuration option to make it so all object paths use subscripting. Thank you

Hi, somehow I haven't noticed this issue before. Do you mean that e.g. {"a": {"b": "c"}} would be a_b? If yes - there's pathSeparator option for it now.
