Defines a transform to be applied to a keras model graph.
A transform is a combination of 'Find + Replace' which describes how to find a pattern of layers in a model, and what to replace those layers with.
A pattern is described using
LayerPattern. The replacement function receives
LayerNode which contains the matched layers and should return a
LayerNode which contains the set of layers which replaced the matched
Dictionary of custom objects introduced by the
Transform may introduce custom Classes and types unknown to Keras. This
function should return a dictionary containing these objects in case such
types are introduced. It allows model construction to serialize/deserialize
|Custom objects introduced by the transform as a dictionary.

replacement( match_layer )
Generate a replacement sub-graph for the matched sub-graph.
The fundamental constraint of the replacement is that the replacement sub-graph should consume the same input tensors as the original sub-graph and also produce a final list of tensors which are same in number and shape as the original sub-graph. Not following this could crash model creation, or introduce bugs in the new model graph.
