[typescript-angular2] feature request NgModule

Description

I think we need to generate NgModule for the generated service

Suggest a Fix

for exmaple

API.modules.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { HttpModule } from '@angular/http';

{{#apiInfo}}
{{#apis}}
{{#operations}}
import { {{ classname }} } from './api/{{ classname }}';
{{/operations}}
{{/apis}}
{{/apiInfo}}

@NgModule({
imports: [ CommonModule, HttpModule ],
declarations: [],
exports: [],
providers: [ {{#apiInfo}}{{#apis}}{{#operations}}{{ classname }}, {{/operations}}{{/apis}}{{/apiInfo}} ]
})
export class ApiModule {}

Start by locating the TypeScript Angular2 generator templates that produce the generated service files, then compare their output with the proposed API.modules.ts example. Done means generated clients include an NgModule that imports the generated services and registers them as providers.
