//! # Deep Neural Network module
//! This module contains:
//! - API for new layers creation, layers are building bricks of neural networks;
//! - set of built-in most-useful Layers;
//! - API to construct and modify comprehensive neural networks from layers;
//! - functionality for loading serialized networks models from different frameworks.
//!
//! Functionality of this module is designed only for forward pass computations (i.e. network testing).
//! A network training is in principle not supported.
