 *
 * Supports:
 *   - Firefox: full stack trace with line numbers, plus column number
 *              on top frame; column number is not guaranteed
 *   - Opera:   full stack trace with line and column numbers
 *   - Chrome:  full stack trace with line and column numbers
 *   - Safari:  line and column number for the top frame only; some frames
 *              may be missing, and column number is not guaranteed
 *   - IE:      line and column number for the top frame only; some frames
 *              may be missing, and column number is not guaranteed
 *
 * 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
 *     Exceptions Have Stacktrace to be enabled in opera:config)
 *   - 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.

 *   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
 *
 * 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).
