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