## Javascript `log` Function

Every time I start a new project, I want to pull in a `log` function that allows the same functionality as the `console.log`, including the full functionality of the [Console API](http://getfirebug.com/wiki/index.php/Console_API#console.log.28object.5B.2C_object.2C_....5D.29).

There are a lot of ways to do this, but many are lacking.  A common problem with wrapper functions is that the line number that shows up next to the log is the line number of the log function itself, not where `log` was invoked.  There are also times where the arguments get logged in a way that isn't quite the same as the native function.

This is an attempt to once and for all document the function that I pull in to new projects.  There are two different options:

* **The full version**: Inspired by the [plugin in HTML5 Boilerplate](https://github.com/h5bp/html5-boilerplate/blob/master/js/plugins.js).  Use this **if you are writing an application and want to create a window.log function**.   Additionally, this will set all the `console` methods to an empty function if they don't exist to prevent errors from accidental `console.log` calls left in your code.  Put this snippet at the top of the rest of your scripts - it will need to be evaluated first thing to work.
* **The portable version**: Use this **if you want to use it inside a plugin** and/or don't want to muck with the global namespace.  Just drop it at the bottom of your plugin and log away.  `log` can be called before the function declaration, and will not add anything to the window namespace or modify the console objects.
