//   Storm.TextEditor.dll
//   ��������������������
//     Storm.TabControl.dll was created under the LGPL 
//     license. Some of the code was created from scratch, 
//     some was not. Code not created from scratch was 
//     based on the DotNetFireball framework and evolved 
//     from that. 
//     
//     What I mostly did in this library was that I 
//     cleaned up the code, structured it, documentated 
//     it and added new features. 
//     
//     Although it might not sound like it, it was very
//     hard and took a long (pretty much a shitload)
//     time. Why? Well, this was* some of the crappiest,
//     most unstructured, undocumentated, ugly code I've
//     ever seen. It would actually have taken me less 
//     time to create it from scratch, but I figured that
//     out too late. Figuring out what the code actually
//     did and then documentating it was (mostly) a 
//     day-long process. Well, I hope you enjoy some of
//     my hard work. /rant
//     
//     Of course some/most of it is made from scratch by me.
//     *Yes, was. It isn't now. :) Some of the naming 
//     conventions might still seem a little bit off though.
