MongoDB appender

Hello,

Your tool is very impressive and I would like extend it to persist log messages in a mongoDB "capped-collections".

I have check your documentation and follow theses steps:

- by adding a mongoose dependency in package.json : 
"mongoose": "3.6.14",
- by adding load of appender in woodman-node.js by example

var MongoAppender = require('./appenders/nodejs/mongoappender');
....
  LogManager.registerAppender('mongo', MongoAppender);
  LogManager.registerAppender('Mongo', MongoAppender);
  LogManager.registerAppender('MongoAppender', MongoAppender);

But I do not know today how to use require in your AMD modules.

Some help needed.

I would like contribute.
