-- Define a variable to hold all the names of the frames that we may find
childlist = {}

--[[
    Go through all the variables defined in global space. RoM by default will 
    create all of its objects (frames, buttons, etc) in global space so this 
    should work. It will not find any objects that are only defined in a local 
    scope however.

    The lua iterator pairs() will iterate through all entries in the given table
    and return the key (name index) of the entry (this is usually a string) as
    well as the entry itself. So here, k will contain the name of the entry and
    v will be the object itself.

  -- figure out if it really is a frame so instead we check if the GetParent entry
  -- exists in this table. If so we'll assume that it is a function and that it is 
  -- therefore a frame (though this could be defeated easily enough)
