mongoose-paginate

When using mongoose-paginate 1.2.0 for pagination I got two following issues:

1. No paginate method on my Model class error

Regarding to the closed "No paginate method on my Model class" issue at #9, I found the problem that the mongoose module initializes new object:
module.exports = exports = new Mongoose; var mongoose = module.exports;so if we use :
var mongoose = require('mongoose'), paginate = require('mongoose-paginate');then the 1st mongoose variable is different from the mongoose variable with extend paginate method inside the mongoose-paginate module.

That why the error "No paginate method" was thrown out.

So I suggest we export the mongoose variable at the bottom of the mongoose-paginate.js:
module.exports = mongoose;

Then we use it as:
var mongoose = require('mongoose-paginate');

2. Mongoose also supports Population where we can get related documents within query - like join in RDBMS so I add it to mongoose-paginate. But I got an error:

"MissingSchemaError: Schema hasn't been registered for model "undefined"

I checked everything -  Schema, Model.. were correct and tested them well with the main Mongoose module (3.8.8) and finally it turned out that mongoose-paginate 1.2.0 is using Mongoose 3.5.1 so then upgraded to 3.8.8 and got it to work.
