/**
 * Cross-browser processing of unhandled exceptions
 *
 * Syntax:
 * ```js
 *   TraceKit.report.subscribe(function(stackInfo) { ... })
 *   TraceKit.report.unsubscribe(function(stackInfo) { ... })
 *   TraceKit.report(exception)
 *   try { ...code... } catch(ex) { TraceKit.report(ex); }
 * ```
 *
 * 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 TraceKit.StackTrace object as described in the
 * TraceKit.computeStackTrace docs.
