The BaseNode is a base class for `Node` and `Node2D`. It should not be used directly unless creating a new transformation type. It is included here to document the common interface of 1D and 2D node and wavelet packet transform classes. Parameters ---------- parent : Parent node. If parent is None then the node is considered detached (ie root). data : 1D or 2D array Data associated with the node. 1D or 2D numeric array, depending on the transform type. node_name : A name identifying the coefficients type. See `Node.node_name` and `Node2D.node_name` for information on the accepted subnodes names.

Notes ----- If nodes at the given level are missing (i.e. the tree is partially decomposed) and `decompose` is set to False, only existing nodes will be returned. Frequency order (``order="freq"``) is also known as sequency order and "natural" order is sometimes referred to as Paley order. A detailed discussion of these orderings is also given in [1]_, [2]_.
