Adding torch examples

[ncguilbeault]

This PR introduces new examples for the Bonsai.ML.Torch package in bonsai-rx/machinelearning#48. A list of examples and brief summaries are provided below.

Examples

Linear Regression

In this example, the Bonsai.ML.Torch package is used to perform simple linear regression using the ordinary least squares technique on simulated data.

Neural Nets - Pretrained Model

This example shows how to run inference using deep neural networks on a typical image classification problem. In this particular example, the pretrained weights of the model are loaded from disk.

Neural Nets - Torch Hub

This example shows how a torch model can be downloaded from pytorch hub and used to run forward inference.

Neural Nets - Training Online

This example shows how a deep neural network can be trained online to solve an image classification problem.

Running On Linux

This example demonstrates how to run the package on Linux.
