(*
This is an example how to write a highlighter from scratch.
See the units for each example highlighter.
This is NOT about extending the IDE. This is about SynEdit and it's Highlighter only.
Therefore this does not include:
- registration in the component pallette.
- Using the Object Inspector
Those steps are the same as they would be for any other self writen componont.
