Indoor navigation based on earth's magnetic field

Summary

This project demonstrates how to use the device sensors - Magnetometer, Accelerometer and Gyroscope in order to create an indoor mapping that would, later on, will be used in an indoor navigation app.

The main project was broken - it was written in Swift 3 and used a framework that doesn't exist in the repository, or anywhere else by its name.
This fork was built in order to deal with those problems.

Fixes I've made:

I replaced the use of Linear.framework with Accelerate and Surge pods to provide the linear algebra functionality that this project so depends on. While doing that I needed to rewrite parts of the math and even reinvent the wheel because I couldn't find some of the math methods in these pods. Apart from this, I also upgraded it to Swift 5(instead of Swift 3) and dealt with a broken project file.

Current State:

The app starts successfully, registers all the sensors and sends the data to its processing unit. Unfortunately, I cannot understand the visual results. part of the reasons are:

1. I don't have a review of the product(how should it look like for example)
2. I might have an error in the math conversion from the Linear.framework to the Accelerate and Surge pods
3. The main project contains bugs.

The purpose of this fork:

If you are interested in such a riddle and thrilled about indoor navigation solutions with no GPS whatsoever then please, please join me on that effort!
