[Suggest] Documentation update

Hi, Thank you for the great library. Just for people that using AOT compilation (typically people that use angular-cli), you have to add the following code to your AppModule in order to work:

In your AppModule:

import {HighchartsStatic} from 'angular2-highcharts/dist/HighchartsService';
import {ChartModule} from "angular2-highcharts";

export function highchartsFactory() {
  return require('highcharts');
}

@NgModule({
   providers:[
   ...
   {
      provide: HighchartsStatic,
      useFactory: highchartsFactory
    },
    ....
]}

In the module where you use the chart directive:

@NgModule({
   imports: [
     ChartModule
   ],
 ]}

You could also declare as a singleton (ShareModule)

Thank you !

How would you load Highcharts modules with this solution? Modules like highcharts/modules/solid-gauge.

Edit: This seems to work for exporting, and for solid gauge:

export function highchartsFactory() {
    var hc = require('highcharts');
    var hcm = require('highcharts/highcharts-more');
    var exp = require('highcharts/modules/exporting');
    var sg = require('highcharts/modules/solid-gauge');

    hcm(hc);
    exp(hc);
    sg(hc);
    return hc;
}

(Added highcharts-more to make solid gauge work)

Yea, would be great. But HighchartsService supposed to be private part of the lib. Are there any simplier approach to achieve this ? I would change something in the lib if it is necessary
