[Documentation] Write proper documentation for the Wiki

[OriDevTeam]

Write an introduction that explains what is the project and why it was done, a guide explaining how loading works, a guide to how to use already existing shaping projects and a guide explaining how the process works

The introduction guide should be very friendly to users that already have notion of how text manipulation works

All sections should have an estimated time of reading, with the goal of reducing time necessary to read, and inform how much time estimate it should take to read

Follows the proposal of the table of contents:

Introduction

• What is CodeShaper
• Using CodeShaper
• Using Shaping Projects

How it works

• Loading
• Processing
  • Visitors
  • Patches
  • Actions
• Output
