bunyan-serializers

Some customized serializers for bunyan.

example

``javascript
var serializers = require('bunyan-serializers');
var bunyan = require('bunyan');

var logger = bunyan.createLogger({
serializers: serializers,
stream: process.stdout,
name: 'test'
});

var server = http.createServer(function(req, res) {
logger.info({req: req, res: res}, 'Got a request and a response');
});
server.listen(8080);
`

differences from bunyan.stdSerializers.

In the standard serializer for bunyan the req- and res-objects are serialized when creating a child-logger, like

`javascript
var child = bunyan.child({
req: reqObj,
res: resObj
});
``
This means that that if the reqObj or resObj get changed after the child has been initated those changes will not be logged properly.
The serializers for req and res-objects are in this project not serialized when a child is created but rather when you actually log.

A serializer for an err-object is also attached for completeness.
