     * TraceKit.computeStackTrace: cross-browser stack traces in JavaScript

     * Syntax:
     *   s = TraceKit.computeStackTrace.ofCaller([depth])
     *   s = TraceKit.computeStackTrace(exception) // consider using TraceKit.report instead (see below)
     * Returns:
     *   s.name              - exception name
     *   s.message           - exception message
     *   s.stack[i].url      - JavaScript or HTML file URL
     *   s.stack[i].func     - function name, or empty for anonymous functions (if guessing did not work)
     *   s.stack[i].args     - arguments passed to the function, if known
     *   s.stack[i].line     - line number, if known
     *   s.stack[i].column   - column number, if known
     *   s.stack[i].context  - an array of source code lines; the middle element corresponds to the correct line#
     *   s.mode              - 'stack', 'stacktrace', 'multiline', 'callers', 'onerror', or 'failed' -- method used to collect the stack trace
     *
     * Supports:
     *   - Firefox:  full stack trace with line numbers and unreliable column
     *               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);
 *     }
