## install

```
npm install call-log
```

## usage

```js
var callLog = require('call-log')

function Cat () {}
Cat.prototype.meow = function (sound) { return sound }

// Add instrumentation to Cat
callLog(Cat)

// Use the cat
var cat = new Cat()
cat.meow()
cat.meow('MEOAAAAWWW!')

// Prints:
// "called meow"
// "called meow", "MEOAAAAWWW!"

```
