//  This is suppose to be a scanned that are used on in a web-based situation
//  I want to achive a syntax-highligter that replaces the text between my codeStarter-point and
//  the end-point with HTML code. An example is this:
//  
// ---- OTHER HTML CODE HERE ----
//  [code]
//      using System;
//      using System.Web;
//      namespace
//      {

//          {
//              public static string test = "blah";
//          }
//      }
//  [/code]
// ---- OTHER HTML CODE HERE ----
