Basic Swift Neural Network Framework

Implementing this framework gives you basic information about how neural networks work.
I have an article about this framework on Medium: https://towardsdatascience.com/neural-networks-on-swift-ba181dcdfde5
Now I am working on a new version of the framework. This version will use Metal Performance Shaders and will be located here: https://github.com/stefjen07/ShadersNeuralNetwork

Framework includes:

• Dense, Convolutional 2D, Pooling, Flatten and Dropout layers;
• Sigmoid and ReLU activation functions;
• Multithreading support.
