Aurelia View Engine Hook for importing enums, static variables, etc

Thanks to a query from Github user @TheNavigateur asking "Allow[ing] import of exported module items into aurelia template, to allow access to static methods, static variables, enums, type definitions, etc. "

and then Rob Eisenberg's example (issue/comments) of how to do this:

	// Here's an example from Rob Eisenberg
	// filename: resources/data/countries.js
	import {viewEngineHooks} from 'aurelia-templating';
	let countries = [
	{ abbreviation: "AF", name: "Afghanistan" },
	{ abbreviation: "AL", name: "Albania" },
	{ abbreviation: "DZ", name: "Algeria" },
	...
	];
	@viewEngineHooks()
	export class CountryBinder {
	beforeBind(view) {
	view.overrideContext.countries = countries;
	}
	}
	// view template filename: account.html
	<template class="user-detail" bindable="controller">
	<require from="resources/data/countries"></require>
	...
	<div class="form-group">
	<label class="col-sm-2 control-label">Country</label>
	<div class="col-sm-3">
	<select class="form-control">
	<option value="" selected="selected">(please select a country)</option>
	<option repeat.for="country of countries" value.bind="country.abbreviation">${country.name}</option>
	</select>
	</div>
	</div>
	...
	</template>
