Class OnlineFlowNode

OnlineFlowNode wraps an OnlineFlow of OnlineNodes into a single OnlineNode.

This is handy if you want to use an OnlineFlow where an OnlineNode is required.
Additional args and kwargs for train and execute are supported.

An OnlineFlowNode requires that all the nodes of the input onlineflow to be either:
(a) OnlineNodes (eg. OnlineCenteringNode(), IncSFANode(), etc.),
 or
(b) trained Nodes (eg. a fully trained PCANode with no remaining training phases. A trained Node's
node.is_trainable() returns True and node.is_training() returns False.),
 or
(c) non-trainable Nodes (eg. QuadraticExpansionNode(). A non-trainable Node's node.is_trainable()
returns False and node.is_training() returns False.).

OnlineFlowNode does not support an onlineflow with a terminal trainable Node that is not
an OnlineNode (see doc string of OnlineFlow for reference).

All the read-only container slots are supported and are forwarded to the internal flow.

Wrap the given flow into this node.

Pretrained nodes are allowed, but the internal flow should not
be modified after the FlowNode was created (this will cause problems
if the training phase structure of the internal nodes changes).

If the node dimensions and dtype are not specified, they will be
extracted from the internal nodes (late dimension setting is also
supported).

flow can have crash recovery enabled, but there is no special support
for it.

Return a training sequence containing all training phases.

Unlike thw FlowNode, the OnlineFlowNode requires only
one train_seq item for each node. Each node's train function
takes care of its multiple train phases (if any).
