eval, nolock: true

[qharlie]

For MongolianDB.prototype.eval it would be nice to have a way to specify nolock , and have the default be nolock = true since it's rare you would actually want it to lock.

I just changed

var command = { $eval:new bson.Code(execFunction, execFunction.scope || {}) }

to read

var command = { $eval:new bson.Code(execFunction, execFunction.scope || {}), nolock: true }
