Detailed Description

This class allows to create and manipulate comprehensive artificial neural networks.

Neural network is presented as directed acyclic graph (DAG), where vertices are Layer instances, and edges specify relationships between layers inputs and outputs.

Each network layer has unique integer id and unique string name inside its network. LayerId can store either layer name or layer id.

This class supports reference counting of its instances, i. e. copies point to the same instance.

       Descriptors have the following template &lt;DFN&gt;&amp;lt;layer_name&amp;gt;[.input_number]&lt;/DFN&gt;:
       - the first part of the template &lt;DFN&gt;layer_name&lt;/DFN&gt; is string name of the added layer.
         If this part is empty then the network input pseudo layer will be used;
       - the second optional part of the template &lt;DFN&gt;input_number&lt;/DFN&gt;
         is either number of the layer input, either label one.
         If this part is omitted then the first layer input will be used.
