Coding Conventions

This file will cover important coding practices that are important to stress when coding this program. Listed below are some of the more important details that should be stressed. Each programmer has his/her own way to deliver code. The importance of having similar coding conventions throughout this program are listed below.

• 80% of the time spent on a piece of software goes to maintenance.
• Hardly any software is maintained for its whole life by the original author.
• Code conventions improve the readability of the software, allowing engineers to understand new code more quickly and thoroughly.
• If you ship your source code as a product, you need to make sure it is as well packaged and clean as any other product you create.

// Some helpers for converting GPS readings from the WGS84 geodetic system to a local North-East-Up cartesian axis.

// The implementation here is according to the paper:
// "Conversion of Geodetic coordinates to the Local Tangent Plane" Version 2.01.
// "The basic reference for this paper is J.Farrell & M.Barth 'The Global Positioning System & Inertial Navigation'"
