The purpose of this demo is to show how to implement the TSynMultiSyn control
allowing you to syntax highlight documents with many highlighters based on
schemes that you define.

I thought it would be a great help by setting up the AutoComplete and
Completion proposal. When running the demo use them to correctly insert the tags
that I setup the SynMultiSyn1.Schemes to look for as Start / End Expression.
