Extend InfinityModel

[snewcomer]

• Expose infinityModel constructor to people to extend in their own apps
• Allow them to pass a class into the infinityModel that should be extended - i.e. as third argument in Route.
• improve documentation (also alluding to Ensure works with JSONAPI pagination requirements #97 as well)
• public getter for infinityModels. Something like route#getInfinityModels()

import InfinityModel from 'ember-infinity/lib/infinity-model';
const CustomInfinityModel = InfinityModel.extend({
  //..snip
})

export default Route.extend({
  model() {
    return this.infinityModel('product, { perPage: 10, startingPage: 1 }, CustomInfinityModel);
  }
})

Ref #220

Will tackle after #220

More notes

// new way

const MyInfinityModelClass = InfinityModel.extend({
  global: service(),
  buildParams() {
    let params = this._super(...arguments);
    params['category_id'] = get(this, 'global.categoryId');
    return params;
  }
});

Route.extend({
  global: service(),
  categoryId: computed('global.categoryId', function() {
    return get(this, 'global.categoryId');
  }),
  model() {
    this.infinityModel('product', {}, MyInfinityModelClass);
  }
});

I'll make sure I get this issue done by the end of next week to add to the 1-0 branch.
