To create system documentation using Sphinx you run
the make.bat file.

It can be run in two ways
   * make.bat html-rst
   * make.bat html

In the first way the .rst files nedded area created first
in the current directory. If the structure of the timeline
project is changed (Files or directories added or removed)
all .rst files should be deleted from this directory prior
to running the make.bat file again.

In the second way it's assumed that the .rst files are already
created and only changes in source code has to be handled.
This way is therefore quicker.

The html pages created as a result, are found in the .\_build\html
directory. The start page is named index.html

Current version of Spinx used is v2.1.0
