Update documentation in few steps

In this document, you will learn how to have a local and updated copy of the documentation on your PC.

First, you have to know that {ROOT}/update-documentation.bat is your ally. But before you run it, you should take some steps first to make it work.

You need some apps, that are the following:

• Doxygen: http://www.stack.nl/~dimitri/doxygen/
• InnoSetup: http://www.jrsoftware.org/isdl.php

By the moment, you can use this only in Windows.

Once installed, you will run it, and you will realize that a lot of windows appear, let them do it work.

When everything is finished a setup will be generated in {ROOT}/Apps/DOCS-FINAL.

Please, install it, and you will have an updated version of the documentation.

And, also, you will have access to quick help in the Editor Inspector of Unity with the derived Types of Lerp2API.

Thanks to review this.

Best regards.
