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());
