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

+ * Syntax:

+ * 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#
+ *
+ * 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).
