Changed all occurrences of `return DataFrame` to `return self._constructor` and changed the latter to return `self.__class__` rather than `DataFrame` by default. Also made static methods like `DataFrame.from_dict` work on the `cls` passed to them rather than on hard-coded `DataFrame`. This is a minimal quick win on the cases described in Issue pandas-dev#2859. A formal approach to make classes friendly to subclassing might still be needed, see discussion in the case.

Quick "hand merge". This won't solve the issue but helps in some cases |
