Because of multiple requests, here now the additional functionality 
"source code folding"

Now everything between
#if REGION
and
#endif

will be set to hidden, the keywords "#if REGION" and the matching 
"#endif" will be marked as read only(collapsed REGION's cannot be 
changed!), if collapse.


These Keywords must not have any leading or ending white spaces!!!

By default, if you open a source file all REGION's will be collapsed.


FOR SAFETY, NO CHANGES WILL BE MADE TO THE SOURCE CODE WHEN EXPANDING OR 
COLLAPSE THE REGIONS!!!



As always, you can also look at the pictures
