Ionic 2: Register custom typings file in RC.0
<p>In beta11 I put my own customTypings.d.ts in the typings folder.<br>
This folder doesn't exist in Ionic RC.0.</p>

<p><strong>Q) So how do I register my custom typings file now in RC.0?</strong></p>

<p><em>e.g. customTypings.d.ts:</em></p>

<pre><code>interface Window {
    plugins: any;
}

declare var SignaturePad: {
    new(canvas: any, options?: any): any;
}

interface CordovaPlugins {
    OneSignal: any;
}
</code></pre>
