Javascript driver for Mongo database

===========

narwhal-mongodb is a CommonJS-compliant JavaScript driver for the Mongo database. It wraps the official Java driver and emulates its behavior, while adding some JavaScript sugar and convenience methods.

Example usage

------------------------

    var MongoDB = require("mongodb");

    var db = new MongoDB.Mongo().getDB("mydb");

    var colls = db.getCollectionNames();

    colls.forEach(function(el) { print(el); });

    var coll = db.getCollection("testCollection");

    coll.drop();

    var doc = {

       "name" : "MongoDB",

       "type" : "database",

       "count" : 1,

       "info" : {

                   x : 203,

                   y : 102

                 }

    }

    coll.insert(doc)

    myDoc = coll.findOne();

    print(myDoc);

    // Now, lets add lots of little documents to the collection so we can explore queries and cursors

    for (var i=0; i < 100; i++) {

        coll.insert({"i": i});

    }

    print(coll.getCount());

    // Let's get all the documents in the collection and print them out

    var cur = coll.find();

    while(cur.hasNext()) {

        print(cur.next());

    }

    // Now use a query to get 1 document out

    var query = { i: 71 };

    cur = coll.find(query);

    while(cur.hasNext())

        print(cur.next());

    // Now use a query to get a larger set

    query = { "i": { "$gt": 50 } };  // i.e. find all where i > 50

    cur = coll.find(query);

    while(cur.hasNext())

        print(cur.next());
