Underlies functionality of other modules within [stacktrace.js](https://www.stacktracejs.com).
Written to closely resemble StackFrame representations in [Gecko](http://mxr.mozilla.org/mozilla-central/source/xpcom/base/nsIException.idl#14) and [V8](https://github.com/v8/v8/wiki/Stack%20Trace%20API)
## Usage
```js
// Create StackFrame and set properties
var stackFrame = new StackFrame({
functionName: 'funName',
args: ['args'],
fileName: 'http://localhost:3000/file.js',
lineNumber: 1,
columnNumber: 3288,
isEval: true,
isNative: false,
source: 'ORIGINAL_STACK_LINE'
evalOrigin: new StackFrame({functionName: 'withinEval', lineNumber: 2, columnNumber: 43})
});
stackFrame.functionName // => "funName"
stackFrame.setFunctionName('newName')
stackFrame.getFunctionName() // => "newName"
stackFrame.args // => ["args"]
stackFrame.setArgs([])
stackFrame.getArgs() // => []
stackFrame.fileName // => 'http://localhost:3000/file.min.js'
stackFrame.setFileName('http://localhost:3000/file.js')
stackFrame.getFileName() // => 'http://localhost:3000/file.js'
stackFrame.lineNumber // => 1
stackFrame.setLineNumber(325)
stackFrame.getLineNumber() // => 325
stackFrame.columnNumber // => 3288
stackFrame.setColumnNumber(20)
stackFrame.getColumnNumber() // => 20
stackFrame.source // => 'ORIGINAL_STACK_LINE'
stackFrame.setSource('NEW_SOURCE')
stackFrame.getSource() // => 'NEW_SOURCE'
stackFrame.isEval // => true
stackFrame.setIsEval(false)
stackFrame.getIsEval() // => false
stackFrame.isNative // => false
stackFrame.setIsNative(true)
stackFrame.getIsNative() // => true
stackFrame.evalOrigin // => StackFrame({functionName: 'withinEval', lineNumber: ...})
stackFrame.setEvalOrigin({functionName: 'evalFn', fileName: 'anonymous'})
stackFrame.getEvalOrigin().getFunctionName() // => 'evalFn'
stackFrame.toString() // => 'funName(args)@http://localhost:3000/file.js:325:20'
