Simple, cross-browser [Error](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error) parser.

This library parses and extracts function names, URLs, line numbers, and column numbers from the given Error's `stack` as

an Array of [StackFrame](http://git.io/stackframe)s. 

Once you have parsed out StackFrames, you can do much more interesting things. See [stacktrace-gps](http://git.io/stacktrace-gps).

Note that in IE9 and earlier, `Error` objects don't have enough information to extract much of anything. In IE 10, `Error`s

are given a `stack` once they're `throw`n.

## Browser Support
