 *   - Opera:   full stack trace with line and column numbers
 *   - Chrome:  full stack trace with line and column numbers

 * In theory, TraceKit should work on all of the following versions:
 *   - IE5.5+ (only 8.0 tested)
 *   - Firefox 0.9+ (only 3.5+ tested)
 *   - Opera 7+ (only 10.50 tested; versions 9 and earlier may require

 *   - Safari 3+ (only 4+ tested)
 *   - Chrome 1+ (only 5+ tested)
 *   - Konqueror 3.5+ (untested)
 *
 * Requires TraceKit.computeStackTrace.
 *
 * Tries to catch all unhandled exceptions and report them to the
 * subscribed handlers. Please note that TraceKit.report will rethrow the
 * exception. This is REQUIRED in order to get a useful stack trace in IE.
 * If the exception does not reach the top of the browser, you will only
 * get a stack trace from the point where TraceKit.report was called.
 *
 * Handlers receive a stackInfo object as described in the
 * TraceKit.computeStackTrace docs.

 * Supports:

 *               number on top frame
 *   - Opera 10: full stack trace with line and column numbers
 *   - Opera 9-: full stack trace with line numbers
 *   - Chrome:   full stack trace with line and column numbers
 *   - Safari:   line and column number for the topmost stacktrace element
 *               only
 *   - IE:       no line numbers whatsoever
 *
 * Tries to guess names of anonymous functions by looking for assignments
 * in the source code. In IE and Safari, we have to guess source file names
 * by searching for function bodies inside all page scripts. This will not
 * work for scripts that are loaded cross-domain.
 * Here be dragons: some function names may be guessed incorrectly, and
 * duplicate functions may be mismatched.
 *
 * TraceKit.computeStackTrace should only be used for tracing purposes.
 * Logging of unhandled exceptions should be done with TraceKit.report,
 * which builds on top of TraceKit.computeStackTrace and provides better
 * IE support by utilizing the window.onerror event to retrieve information
 * about the top of the stack.
 *
 * Note: In IE and Safari, no stack trace is recorded on the Error object,
 * so computeStackTrace instead walks its *own* chain of callers.
 * This means that:
 *  * in Safari, some methods may be missing from the stack trace;
 *  * in IE, the topmost function in the stack trace will always be the
 *    caller of computeStackTrace.
 *
 * This is okay for tracing (because you are likely to be calling
 * computeStackTrace from the function you want to be the topmost element
 * of the stack trace anyway), but not okay for logging unhandled
 * exceptions (because your catch block will likely be far away from the
 * inner function that actually caused the exception).
 *
 * Tracing example:
 *     function trace(message) {
 *         var stackInfo = TraceKit.computeStackTrace.ofCaller();
 *         var data = message + "\n";
 *         for(var i in stackInfo.stack) {
 *             var item = stackInfo.stack[i];
 *             data += (item.func || '[anonymous]') + "() in " + item.url + ":" + (item.line || '0') + "\n";
 *         }
 *         if (window.console)
 *             console.info(data);
 *         else
 *             alert(data);
 *     }
