A way to automate mongoose model methods mapping

[vladyslav-dotsenko]

It would be pretty cool to make restifyMongoose resource support custom model methods and improove restifyMongoose::serve function to automatically generate api endpoint for those methods.
For example:
When we have model...

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const _schema = new Schema({
  title:  String,
  toggle: { type: Boolean, default: false }
});

_schema.methods.switch = function () {
  this.toggle = !this.toggle;
  this.save();
};

var Toggler = mongoose.model('Toggler', _schema);

... it would be great to generate endpoint /Toggler/:id/switch wich will call appropriate method.
