and tidied up some of the javascript. It includes a basic file logger, with log rolling based on file size, and also replaces node's console.log functions.
NOTE: in v0.2.x require('log4js') returned a function, and you needed to call that function in your code before you could use it. This was to make testing easier. v0.3.x make use of [felixge's sandbox-module](https://github.com/felixge/node-sandboxed-module), so we don't need to return a function.
configuration file (`log4js.configure('path/to/file.json')`) explicitly, or just let log4js look for a file called `log4js.json` (it looks in the current directory first, then the require paths, and finally looks for the default config included in the same directory as the `log4js.js` file).
An example file can be found in `test/log4js.json`. An example config file with log rolling is in `test/with-log-rolling.json`
A connect/express logger has been added to log4js, by [danbell](https://github.com/danbell). This allows connect/express servers to log using log4js. See example-connect-logger.js.
